Similar things are/were done in other places as well. When the swiss army retired their Rak Rohr 80 (a license built version of the belgian RL-83 Blindicide), a number were turned over to civilian operators (usualy the guys runing the ski lifts) for this use. However this was in general replaced by droping charges from a helicopter as this is considred to be saver and more reliable.
Just saw a video of a Vietnam veteran telling funny stories. One was a guy who didn't realize that the back side of a Claymore isn't a great place to be. His eyebrows grew back in time.
I completed the course on the 106 RR in the Canadian Army in 1968. The weapon was extremely accurate when using the .50 cal. spotting rifle. Being able to mount it on a jeep was crucial because you had to get the hell away from where you fired it. ''Target 12 o'clock Heat, group of three tanks center tank, on''. Made a real big bang.
I was around these in the NZ army in the 1980’s. They make quite the bang and it’s a real visceral experience to have the blast wave roll through you. One for the gun geeks, the vent holes at the back do not face straight backward. They have a slight twist, so as well as cancelling the recoil from the projectile the gases also cancel the torque imparted on the gun from round moving from rest to rotating via the rifling. I have an expended 106 shell case in my lounge, with LED lights inside it. Looks quite cool at night.
We used them in the Canadian Army reserve back in the 80s as well. I taught antitank back then, so that feeling you get when you push the plunger and fire the main and the shockwave passes through you is more than familiar to me. Probably a major contributor to my tinnitus as well.
@@rickmiddleton9536 lol me too re tinnitus. Funniest story was probably a first time shooter calling “spotter” (meaning he was about to fire the 0.50 spotting rifle) and then pressing instead of pulling the firing knob. Instead of the expected spotter pop, Kaboom, off it went and everyone looks a bit surprised. That cost him a round of drinks afterwards
It also shows you the gun actually moves forward 1ft or so (second slo-mo shot). Ian evidently wasn't talking shit when he said the rounds needed to be properly balanced -- I'm guessing this one was slightly too heavy?
Hell , was your Grandpa an Antitank Man ??? We used to stand facing the “ Backblast Area “ and shout The Command’s given by your Section Sgt . : Backblast Area All Clear !!! ,Standby To Fire The 106 !!! Fire The 106 !!! And we used Wax Plugs and in Combat Cigarette Butts !!! None of that Fancy smancy Ear muffs/ Phones like they got today !!! The commands was to keep Equal Pressure in your ear’s and sinuses !!!
I had a friend of mine, who was in Veitnam, he also was an ONTOS gunner. He told me that two of the guns could be dismounted and used the same mount on the ground.
In weapons demonstration during Marine Corps bootcamp we witnessed a 106 recoiless rifle knock the turret off an old Sherman tank. Will never forget the 50 caliber spotting system on the 106 let alone the awesome power of the 106.
When I used to instruct on the use of this weapon, the first demonstration on the range was to put a couple of the wood packing crates that the ammo came in into the backblast area about 20' behind the gun and then fire off a round. The crates would generally not take this treatment well. Which served the purpose of illustrating to the course candidates being taught why you stayed the fuck away from the area behind the gun. This was referred to as the BBDA, backblast danger area.
Ha yes. I think all of New York city would be sufficiently destroyed. They did that very juxtaposition for Operation Ivy, the first hydrogen bomb, and it basically swallowed the city and rose miles above it.
For about two years (1985-87) I was a 2nd lieutenant in charge of a platoon with 4 106mm recroiless rifles with 5 jeeps, one for each rifle and one as my command jeep in the Army of Taiwan. Thank you for this video. Bring back lots of fun memory. By the way, in reality we can't use a rope to fire and had to stay really close including the gunner who has to sit right by the rifle aiming at tanks/targets with the optics. The tactics is that two sequential shots the most then we had to move the jeep and rifle away from the spot, because enemy tanks can easily spot the kick off dust around us.
Brings back old memories. We got a demonstration of one of these in boot camp, 76, with two empty ammo crates stood behind the gun. They were splinters, with a direct hit, downrange back then, kind of awe inspiring. Thanks for this. Semper Fi.
think I saw, heard and felt one of these in boot camp when we got taken up to the hills of Pendleton for some infantry training. remember the term "106" and I saw the tracer spotter rnd fly before the big shell which took off a huge chunk of a hill. Semper Fi
@wyomarine just because it was primarily used in ground mounts in one conflict doesn't mean that is how everyone experienced using them. Ian said in the video that there were multiple different vehicle mounts, including at least one model of jeep.
@wyomarine You and Michael are saying the same thing - that they were used in both roles. Calm down man. You raise the question of ‘why not learn something from vets’, but in the same comment go on to insult the people you’re supposedly educating... Maybe if we didn’t have arrogant pogues like you insulting people over the internet over trivial shite like this, we’d have a more ‘educated’ populace with a better understanding of our military history 🤷🏼♂️
wyomarine I agree with you on the keyboard warrior points, but I don’t see anyone arguing here; only Squid saying he’d never seen it on a ground mount before. Again, educate rather than criticise. Or better yet, just don’t engage - ignorance is always gonna be rife in the comments of this type of video
I learned how to operate that thing in 1974 when the Army had them mounted on jeeps. Pretty impressive lined up on the range. The old joke - What are the three sounds a 106 makes? Ping (spotter round). OMG! (tank cdr knows he's dead meat). Boom! Friend of mine later used one to sink a ship in a certain Central American country.
I was in the Battle of Hue City with the First Marines in 1968. I must of fired 100 plus rounds just in that battle. My ears are still ringing almost 55 years later. There is a video of me jumping on the "mule" and firing the gun at the NVA. Your video brings back some good and some bad memories.
Great Job, in 1977 after boot camp I was ordered to USMC Infantry Training School, where I was assign to the weapons platoon of Bravo company, my MOS was 0351 Anti tank Marine. This is the same anti-tank rifle we used and trained on. Oh the memories came flooding back. We were either the last or one of the last platoons to train on this weapon, after that it was the TOW and Dragon.
Man I love Ian's AT gun content. Regardless of country of origin or manufacturer, the design challenge of "we need a rifle powerful enough to stop a tank" seems to have consistently produced some of the coolest and craziest weapons of the twentieth century. Great stuff!
I graduated Paris Island in early September of 76 and reported to my first grunt unit at Lejuene later that month. During initial infantry training we got to observe the 106 recoilless being fired. To emphasize the back blast, the range NCO's put an ammo crate about 100-150 feet behind the firing line. When the gun went off, the crate was completely disintegrated! They didn't have to say much after that.
For anyone interested: There was a former Koren racing mare who was purchased to carry ammunition for these. She got the name Reckless (from "recoilless") and was excellent at her role. She reached the rank of sergeant and even got decorated at the White House.
@@68walter Well, yeah, Ian's vid didn't give a true sense of how the M40 was employed in combat. THE gunner sat on one leg of the mount hunched over the sight and operating the co-axial spotting gun (M8C BAT 50, cal) atop the main gun - this was all on the left side. Opposite the gunner stood the loader facing aft no more than a foot or two away from the vents at the breech. When you touched off the main round it motivated you right down to the molecular level it was widely recognised to cure both constipation and hearing.
THANK YOU FOR THIS REVIEW!! My pop saw a lot of combat in Korea and I remember him speaking of recoilless rifles at times, and they always intrigued me on how they worked, and I never understood how. Now I have a better understanding.
I was at San Diego MCRD in November 1974 graduation 13 weeks later 10 days RNR then training at camp Pendleton. MOS 0351 Antitank assault man. I shot a 106 recoilless rifle many times before 20 days RNR then sent to the South Pacific duty on float 13 months during Cambodia genocide
In Jan 1972 I went through Basic & AIT Training at Ft Jackson, SC. My MOS was 11-Hotel (crew served weapons) with the main weapon we trained on was the 106 RR. Pull the tracer round to check your aim, make adjustments if necessary then push for Boom. Training was super fun until we had to dig a bid ass hole and ramp to hide the jeep that carried the 106.
A coworker of mine has a story about being in the Vietnam war. He was a marine pilot stationed at an airbase (he told me which one and when but I just don't remember). During their offtime, they kept bugging the ONTOS crew guys to let them fire off the recoilless rifles. So they finally got them to drive out a bit into the jungle on a "training" exercise to fire off the guns. The ONTOS guys explained how it worked and let each of the pilots fire off a round from the weapons. Afterward, they are milling around emptying a cooler full of beer. When somebody looks behind them and they find a dead Vietcong Soldier with a radio and binoculars. Apparently, this guy was hidden there watching the base. It was just his bad luck that a bunch of marines out screwing around with an ONTOS happened to pull up right next to him and kill him with the backblast.
In the jear before I joined to the army had been an accident with that gun. The load gunner rattled his sermon about loadet, desecured, dangerous area free, ready, and the aim gunner fired. 6yards behind the gun, in the lethal triangle, was a recruit. After the shot the head, still in the helmet and with the ear protectors on, was in safety distance of 30 yards and somewhere between the torso and the separate legs. A second chance isn't in such a situation.
“Be nowhere near the back of this gun, ok let’s shot it “ next thing you see a pickup truck slightly sideways the back of the gun haha , Ian its the number one ! I grew up seeing these rifles along other artillery since My father was an army officer, I remember being 6-7 years and head straight the gun storage to play with them , traverse elevation and breech operation, what a time
I love how after firing the first round, the only thing anyone can think of to say is "Holy shit!". Absolutely tremendous blast wave from both sides of this beast.
Ian, how about a video on how Hamilton and Sons and Drive Tanks go about reloading these large caliber rounds? Curious about what types of powder they use, the priming, and where they come by the projectiles.
That high speed shot reminds me of every sci fi movie where something happens and all the little stones on the ground slowly levitate to add dramatic effect.
that was awesome at 8:46 i've seen alot of high speed firearm shots. many on this channel, but that one was the best. it was only a sec or 2, but you can see the shell spinning with the smoke twisting behind it. most of the time the shell is just a streak, and that all you see. not that time. that was awesome
First saw it used at Fort Polk Louisiana about 1975. They had it mounted to a jeep, standard mounting at the time. It would fire a huge 106mm round down range. The man pack 90mm was used with Infantry up into the end of the seventies. Unlike the 90mm this big 106mm fired at a range of up to 2kms. It used a 50Cal in a barrel along the type. Once the 50 cal tracer, hit you knew your were dead on...then the big kaboom and flash. Later our Anti Tank Platoon had this mounted onto the top of a M113 APC.. good idea because when mounted to a jeep it would tend to be severely top heavy and often men flipped them and injuries ensued. Down side to the 106mm, it made a huge signature, noise and dust at the point of firing...dead give away to the T-62 and you could be sure you gathered lots of attention. So fired in pairs against a lead tank, very effective... survivability??? well.... you got one tank... Ha ha! Later in Korea we were issued TOW anti Tank Weapon in anti Armor Sections. TOW: Tube launched, Optically sighted, Wire guided. TOW's max range was high classified, but easily a 2km bad News post card for Korean T-55s of the time. It was lethal, but TOW clearly solved many of the problems of the 106mm...
@UCQDXeBcBtYEzDh7PlBHmbYA If Wikipedia is to be believed, it totally is possible and it leads to spectacular results: > The [Ontos] was taken to the Aberdeen Proving Ground where single rifles had been tested earlier. When all six weapons were fired at once, the back blast from the firing knocked bricks out of a nearby building and knocked the rear windows out of several cars.
Can you fire a full broadside from an Ontos without rolling it over? The Iowa class battleships reportedly were recommended to fire a full broadside at once because of this effect
I remember being at a fire power demonstration held by the National Guard in the early 1970s; they set up a pile of wooden ammo crates a few yards out behind the gun. The target was a tank hull with turret about 400 yards down range. They fired the round after checking with the .50 cal spotting rifle first. When the shell hit the tank, fire shot out of every opening on it. The back blast was incredible, when it cleared, all the ammo crates were simply gone and a team went over and put out a couple small ground fires. Amazing stuff.
I was trained on the 106 in SFQC in 1988. I believe it still may be taught (and fired) there. In 1989, I gave instruction on these weapons to the Honduran army, who mounted them in their jeeps.
Outstanding! 106 RR was my MOS in the army. Standing next to the breech is a very intense experience. The ones that we used had a 50 cal tracer on it. Once you fire it you gotta move that jeep because there is no hiding where the round was fired from. GREAT VIDEO!!! Why you boys standing so far away when your firing it? Lolololololol! The loader had to stand right beside the breech. It's an experience you won't soon forget! Kevin O'Rourke
Thanks for the video. In the 60's my MOS was 112 heavy weapons which included 4.2 mortar and the 106 recoilless I remember having to stand beside the breach at attention when the 106 was fired during training. I feel it wasn't the 106 that did in my hearing but the crack of the 50 cal. when sighting in for use. Again thanks for the memories
That backblast is insane. I've heard of artillery crew members getting smacked by the action recoiling backwards on standard artillery, but this is a whole different ball game.
While attending Officer's Candidate School (OCS) each student was able to aim the spotting rifle to get-on-target and then fire a round. Lots of fun, but loud with minimal ear protection of those times (1962). It is impressive to see the .50 cal rounds traveling to target, and then watch the 106mm round follow on the same trajectory, but slightly 'slower' than the .50 cal round. The tank HEAT rounds look like flying cantaloupes going down range ... :)
I remember going to work with my father in the early 70's at the Corpus Christi National Guard armory and playing with the M40's mounted on Jeeps. They did have the spotting rifles on them. They looked like a couple of tubes welded together. Good times.
Actually they look like a bigger M3 grease gun. I was in that unit, HHC 2nd Bn 141st Inf, from about 1979 til I transferred to the State NG HQ to work in the Small Arms Readiness Training Section as the Operations NCO there. Prior to that I was a 106mmRR gunner at Ft Hoodlum and a TOW II gunner in Germany.
When I was in a Marine Corps infantry battalion in the early 1970s, the weapons platoon had these things mounted on mules as our anti-tank guns. It must have taken real courage to fire one of these things at a tank knowing that if you missed, well, I'll leave that unsaid. I never saw one fired, so thanks Ian for filling that gap in my experience.
M50 Ontos video Ian!! You mentioned it now you have to!! They have one on display at Rock Island Arsenal the military base. They let you right on the grounds if you are a tourist.
This is great. My Dad used to operate one of these in the Marine Corps and told me stories about it, but this the first time I've actually seen one in operation.
zoiders , I have some interesting photographs. No, not necessarily wombats. The test area at an airfield in souther England. Can’t remember if it was JATE, AFTDU, AFDC OR AATDU. Different military systems being tested in different aircraft.
@@dallen521 Boards.4chan.org/k/catalog. It's a forum for discussing weapons and military hardware. They can be a bit weird at times but it's a good place to talk and share pictures without having to create an account. Might be worth a check. Old military photos would probably be appreciated there.
If you live on a large lot of land and set this thing off anywhere, I think everyone would involuntarily pause for at least a couple seconds which might buy you something.
I have an M38A1C, which is the converted M38A1 Jeep to carry this weapon. (The later Ford M151, which was used extensively in Vietnam also had heavy modifications.) The conversion for the M38A1 to M38A1C was: "Remove rear seat, discard" which always made me chuckle. Cutting out the back of the body, and welding in angle iron to support it. The windshield was changed out to one with a slot in the front for the barrel. Installation of a barrel mounting clamp on the dash, to hold the barrel while in transit. And there was a conversion of installing coil-over springs in addition to the leaf springs in the rear, the kit installed brackets on the frame (some drilling required), and brackets on the axle, which housed the springs to support the additional 575 pound weapon. Other smaller notes were that the "open" shackles were changed to "close" shackles on all 4 leaf springs, and the installation of ammo racks in the back floor. Additionally, the kit included mounts to change the position of the jerry can and spare tire to the sides of the vehicle - however these were not always installed. I suspect to save on weight. Because this vehicle got heavy with all of the modifications. I could still get up to 50mph+ on flat level smooth roads, but going uphill on modern freeways and highways getting bogged down to 25mph or less is frankly dangerous.
I was in D Troop, the ground troop, of 8/1 Air Cav Squadron at Ft Knox in the early 70's, and every platoon had one of these mounted on a jeep (with a modified windshield so the barrel could be stored facing forward), a 5/4 truck with a mortar (plus the platoon Sgt), and a bunch of jeeps with M60's on pintle mounts. Every now and then we set one up for a demo for the officers going through the Armor School, stack a bunch of wooden ammo boxes behind it, and fired it off. It turned out to be really, really good at making toothpicks.
My grandfather was a U.S. Marine in Vietnam and used to talk about these things, I even found some of his paperwork once. Thank you Ian for finding and shooting one!
PT's Sleepy Corner Could you imagine having a modernized version of the Ontos in Iraq after the last invasion? The same six M40’s, lasted designators for the weapon have been around for years to replace the spotting rifle, maybe a couple HMG’s for gunfire support too. Modern diesel power plant, maybe use that flexible rubber track you see on a lot of farm tractors instead of a the usual metal linked tracked
The Marine Corps unit that I was with Second Battalion Fourth Marines,Based out of Camp Foster Okinawa Japan in 1977 .Had these guns And had M-274 Mules to mount them on. As well as the mount shown in the video . I got to move them around as well as all the ammunition . in the M-561 Gamma Goat I was assigned .They were quite a site to see .
And O By The Way - while it is safe to stand to the flank of a recoilless rifle, and quite close to it, there is a "sweet spot" a few paces to the flank of the barrel mid-point, where the shockwaves of muzzle blast and back blast meet. It is THE place to stand your ear-muffed spectators, if you want to see them stunned and floored by the combined impacts, Equally, it's a bad place to site your Jeep/ 4 x 4 if you like the windshield to stay in one piece and where its designers placed. Same applies to the shape of the exterior body panels. Trust me on this.
Trained on the 106 in the SADF in '86 and '87. Brings back memories. When you fired the sucker it felt like you got punched HARD through the face! Not a good idea to shoot with a hangover.
I was in the infantry in Germany in the mid-60s, and our unit had these... All ours were Jeep-mounted. Pretty spectacular to watch... We also had the shoulder-fired 90mm RR.
The Ontos wasn’t a “repurposed” tank, it was designed from the outset to carry 6 of these weapons as an anti-tank vehicle, a lot of people claim it found its true purpose as an anti-personnel weapon during the Vietnam war.
@@spysareamyth Hey when you got 50,000 screaming Charlies coming at your position you would want to be pointing a bunch of these bad boys at them to ya know.
Purge Blade #231 Look up a round called the Beehive Anti-Personnel Round, a 105mm round packed with flechettes, that was used in Vietnam, imagine 6 of those rounds fired into an area at the same moment, that would be about as anti a person as a round could get.
@@spysareamyth The NVA were not known for employing armor, and you use what you have. True purpose is debatable. Used to good effect in a secondary role is probably the most balanced way to state it. Also, he said repurposed tank chassis, which is different from repurposed tank. I do not know it it's true either way, but it is different. USPS city mail LLVs(Long Life Vehicle - the small boxy mail trucks you've probably looked at and not seen hundreds of times) are, or at least were, built on a Chevy S10 chassis, but no one would call them repurposed S10s.

I always thought the M50 Ontos was the second-least-appreciated armored vehicle after the M113 ACAV. Lighter and cheaper than a tank, but with a hell of a punch.
@@gunmnky That just gives you an excuse to get the whole thing behind cover before someone blows you up. "Well, gotta reload, no need to stay in the line of fire!" And it still beats the hell out of the Sheridan deathtrap. When the crews would rather sit on the _outside_ of the tank than the inside, you seriously screwed up your design.
I qualified with the 106 mounted on a jeep with a 50 cal spotter, when in dought pull out for the 50 and push for the 106 ,the concept for this weapon was a hit and run mission like the man said once fired the enemy knows where you are hence hit and run
Good description of this weapon system. I was a Ski Patrolman at Alta. UT and a Forest Service Snow Ranger in Big and Little Cottonwood canyons for two decades. Over those years I spent many many gun crew missions on the 105 and 106 recoilless. I also got to shoot 75 recoilless and pack howitzers. What a great experience doing avalanche mitigation with these weapon systems. Dave
About 1981, My employment was to help finish and assemble the 106mm recoilers rifles. We also manufactured the barrels, breech blocks, and the main chamber. We were especially careful to deburr the firing pin and its hole to insure that the firing pin could not hang up as it was extremely dangerous to open the breech block with a stuck firing pin. I learned a lot about the M40, but was never able to fire one. I wish I still had the original manufacturing drawings.
Fun side note: They were still in use in the US untill a couple of years ago for avalanche control by the Forest Service, to create artificial avalanches on hillsides where they threatend roads etc.

There's no such thing as an artificial avalanche 😁
And they were only replaced after two accidents blew them up.

With that thing you also have to keep the breech pointed in a safe direction!
"Aim away from face."
Unless they are coming for you if their is a bunch point the back blast in the enemies direction :)
So keep it pointed towards the enemy targets, safe as possible.

Yeah, me too. If it still exists someone, somewhere will invite Ian to show case it.
I know that gun. He did do a video on it. Look up .50 spotting rifle
In which we learn that “low recoil” is not the same as “gentle.”
Recoil-Less. Like stainless, or painless. Less stains, not StainFree
The recoilless is really relative. Such weapons are violent to the extreme in concussion and noise when firing.
I was around these in the NZ army in the 1980’s. They make quite the bang and it’s a real visceral experience to have the blast wave roll through you. One for the gun geeks, the vent holes at the back do not face straight backward. They have a slight twist, so as well as cancelling the recoil from the projectile the gases also cancel the torque imparted on the gun from round moving from rest to rotating via the rifling. I have an expended 106 shell case in my lounge, with LED lights inside it. Looks quite cool at night.
Now that is heavy info, without that this thing might flip over side ways.
We used them in the Canadian Army reserve back in the 80s as well. I taught antitank back then, so that feeling you get when you push the plunger and fire the main and the shockwave passes through you is more than familiar to me. Probably a major contributor to my tinnitus as well.

I’d evacuate my gasses too if that thing went off nearby.
It also shows you the gun actually moves forward 1ft or so (second slo-mo shot). Ian evidently wasn't talking shit when he said the rounds needed to be properly balanced -- I'm guessing this one was slightly too heavy?

The slow mo shot where you see the round spinning out the front is so cool.
i actually went back and watched that a few times, because i saw it and said "Wait a minute, was that the f***ing projectile?!"
Should have had Paul Harrell to help with the intro “we’re on the range today so please bare with gunfire”
Did anyone else think that he might have been too close to that steel being plinked?
We´ll be the judge.
Some tweaks to the audio compressor might help (the sound spikes were making it attack too fast and back off too slow).
Ryan Smith - "please bare with gunfire"
Well, I'm pretty sure the backblast could rip some clothing off...
Paul would test it against the meat target.
Grandpa got a kick out of this, started talking about the differences between the 106 and 105. Cool to see him brought back to his service days
Hell , was your Grandpa an Antitank Man ??? We used to stand facing the “ Backblast Area “ and shout The Command’s given by your Section Sgt . : Backblast Area All Clear !!! ,Standby To Fire The 106 !!! Fire The 106 !!! And we used Wax Plugs and in Combat Cigarette Butts !!! None of that Fancy smancy Ear muffs/ Phones like they got today !!! The commands was to keep Equal Pressure in your ear’s and sinuses !!!
That projectile spinning off to the distance @ 8:45 would really need Zoidberg's "woopwoopwoop" sound effect

underrated comment
I love it when he says “I’ll make a video on it when I find one” and two years later he finds one
I had a friend of mine, who was in Veitnam, he also was an ONTOS gunner. He told me that two of the guns could be dismounted and used the same mount on the ground.
In weapons demonstration during Marine Corps bootcamp we witnessed a 106 recoiless rifle knock the turret off an old Sherman tank. Will never forget the 50 caliber spotting system on the 106 let alone the awesome power of the 106.
Did he mention what happened if you fired all 6 at once?
The tank would vaporize I suppose...or get blasted to a parallel universe! Lol
That's the beauty of it. Because there's no recoil, you could (I believe) fire all six shots in a volley-shot-from-Hell kind of way. xD
@@StressmanFIN The overpressure from doing so might be dangerous.
When I used to instruct on the use of this weapon, the first demonstration on the range was to put a couple of the wood packing crates that the ammo came in into the backblast area about 20' behind the gun and then fire off a round. The crates would generally not take this treatment well. Which served the purpose of illustrating to the course candidates being taught why you stayed the fuck away from the area behind the gun. This was referred to as the BBDA, backblast danger area.
Good idea, a single graphic illustration would work better for me then a dozen lectures
Well, I was _not_ expecting to see this title!
Next year: 'Tsar Bomba History and Firing'
"Just for comparison's sake, we've juxtaposed the blast with the New York Skyline."
LOL
Ha yes. I think all of New York city would be sufficiently destroyed. They did that very juxtaposition for Operation Ivy, the first hydrogen bomb, and it basically swallowed the city and rose miles above it.
"Oh and make sure not to be anywhere within a hundred mile radius when firing one of these babies."
@@Tekdruid They had to downtune the bomb, just so the (specially modified) Tu-95 dropping it would have time to GTFO before the blast.
For about two years (1985-87) I was a 2nd lieutenant in charge of a platoon with 4 106mm recroiless rifles with 5 jeeps, one for each rifle and one as my command jeep in the Army of Taiwan. Thank you for this video. Bring back lots of fun memory.
By the way, in reality we can't use a rope to fire and had to stay really close including the gunner who has to sit right by the rifle aiming at tanks/targets with the optics. The tactics is that two sequential shots the most then we had to move the jeep and rifle away from the spot, because enemy tanks can easily spot the kick off dust around us.

Brings back old memories. We got a demonstration of one of these in boot camp, 76, with two empty ammo crates stood behind the gun. They were splinters, with a direct hit, downrange back then, kind of awe inspiring. Thanks for this. Semper Fi.
think I saw, heard and felt one of these in boot camp when we got taken up to the hills of Pendleton for some infantry training. remember the term "106" and I saw the tracer spotter rnd fly before the big shell which took off a huge chunk of a hill. Semper Fi
Mad respect for the poor souls that had to operate those monstrous things in combat.
I'd much rather be the poor soul with one of those in the back of the Jeep than the poor soul without!
i think we found a use for that proverbial ten foot pole. still, holy shit...
@wyomarine just because it was primarily used in ground mounts in one conflict doesn't mean that is how everyone experienced using them. Ian said in the video that there were multiple different vehicle mounts, including at least one model of jeep.
@wyomarine You and Michael are saying the same thing - that they were used in both roles. Calm down man. You raise the question of ‘why not learn something from vets’, but in the same comment go on to insult the people you’re supposedly educating... Maybe if we didn’t have arrogant pogues like you insulting people over the internet over trivial shite like this, we’d have a more ‘educated’ populace with a better understanding of our military history 🤷🏼♂️
wyomarine I agree with you on the keyboard warrior points, but I don’t see anyone arguing here; only Squid saying he’d never seen it on a ground mount before. Again, educate rather than criticise. Or better yet, just don’t engage - ignorance is always gonna be rife in the comments of this type of video
I learned how to operate that thing in 1974 when the Army had them mounted on jeeps. Pretty impressive lined up on the range. The old joke - What are the three sounds a 106 makes? Ping (spotter round). OMG! (tank cdr knows he's dead meat). Boom! Friend of mine later used one to sink a ship in a certain Central American country.
Ya, I remember it well, played with these babies late 70's. Spotter "ping", next command "stand by"" BOOM.
Tell me more about that
Was it Dominican Republic
Not even enough time for the tank crew to lose their shit.
3:35 very satisfying chunk when the sound of the breech closing reverberates through the barrel out to the venting holes.
I was in the Battle of Hue City with the First Marines in 1968. I must of fired 100 plus rounds just in that battle. My ears are still ringing almost 55 years later. There is a video of me jumping on the "mule" and firing the gun at the NVA. Your video brings back some good and some bad memories.
It's whisper quiet. Doesn't even need a suppressor at that volume!

To be fair, without a suppressor, no one around without protection will ever hear anything again, so...😅
Wow! You got all that juice from one bag of oranges?

Great Job, in 1977 after boot camp I was ordered to USMC Infantry Training School, where I was assign to the weapons platoon of Bravo company, my MOS was 0351 Anti tank Marine. This is the same anti-tank rifle we used and trained on. Oh the memories came flooding back. We were either the last or one of the last platoons to train on this weapon, after that it was the TOW and Dragon.
Man I love Ian's AT gun content. Regardless of country of origin or manufacturer, the design challenge of "we need a rifle powerful enough to stop a tank" seems to have consistently produced some of the coolest and craziest weapons of the twentieth century. Great stuff!
I graduated Paris Island in early September of 76 and reported to my first grunt unit at Lejuene later that month. During initial infantry training we got to observe the 106 recoilless being fired. To emphasize the back blast, the range NCO's put an ammo crate about 100-150 feet behind the firing line. When the gun went off, the crate was completely disintegrated! They didn't have to say much after that.
"You got some gun on your backblast"
For anyone interested: There was a former Koren racing mare who was purchased to carry ammunition for these. She got the name Reckless (from "recoilless") and was excellent at her role. She reached the rank of sergeant and even got decorated at the White House.
There hasn't been a day in the past 52 years when I haven't heard the Damned 106 roaring in my ears,
gary guymon, I guess you were a bit nearer to the gun when firing🙂
LMAO weapons co. 1st bn 5th Mar div...
@@68walter Well, yeah, Ian's vid didn't give a true sense of how the M40 was employed in combat. THE gunner sat on one leg of the mount hunched over the sight and operating the co-axial spotting gun (M8C BAT 50, cal) atop the main gun - this was all on the left side. Opposite the gunner stood the loader facing aft no more than a foot or two away from the vents at the breech. When you touched off the main round it motivated you right down to the molecular level it was widely recognised to cure both constipation and hearing.
Me too. ITS 1973-74
Donn Burge yo
Ya did it Ian. You finally got the spotting rifle on camera. GG
8:41 That was my same reaction as well.
The round spinning out of the barrel was pretty cool in slomo as well.

THANK YOU FOR THIS REVIEW!! My pop saw a lot of combat in Korea and I remember him speaking of recoilless rifles at times, and they always intrigued me on how they worked, and I never understood how. Now I have a better understanding.
I was at San Diego MCRD in November 1974 graduation 13 weeks later 10 days RNR then training at camp Pendleton. MOS 0351 Antitank assault man. I shot a 106 recoilless rifle many times before 20 days RNR then sent to the South Pacific duty on float 13 months during Cambodia genocide
Honorable discharge at Treasure Island and now 60 percent loss of hearing. That rifle was very loud.
I get hungry when Ian says trunnion.
Isn't that trunyon though?
Funion?
Hungry for a trunnion sandwich, huh? Me too...
Truffels and onion ;)
Seared trunnion of beef with a red wine and plum jam reduction
In Jan 1972 I went through Basic & AIT Training at Ft Jackson, SC. My MOS was 11-Hotel (crew served weapons) with the main weapon we trained on was the 106 RR. Pull the tracer round to check your aim, make adjustments if necessary then push for Boom. Training was super fun until we had to dig a bid ass hole and ramp to hide the jeep that carried the 106.
How much did the barrel weigh? Ian gave the total weight but didn't break it down.
That's when you make friends with a combat engineer unit and have them use their bulldozer to make your revetments.
I think the first 10 meters behind this thing ar even more dangerous then the one in the front!
Martin L : “Recoilless rifles aren’t.”
We used to put an ammo box about 10m behind one during demonstrations. Turn that 1/2” pine into toothpicks....
And you got noise coming from both ends.... these couldn't have been pleasant to shoot for any crew.
A coworker of mine has a story about being in the Vietnam war. He was a marine pilot stationed at an airbase (he told me which one and when but I just don't remember). During their offtime, they kept bugging the ONTOS crew guys to let them fire off the recoilless rifles. So they finally got them to drive out a bit into the jungle on a "training" exercise to fire off the guns. The ONTOS guys explained how it worked and let each of the pilots fire off a round from the weapons. Afterward, they are milling around emptying a cooler full of beer. When somebody looks behind them and they find a dead Vietcong Soldier with a radio and binoculars. Apparently, this guy was hidden there watching the base. It was just his bad luck that a bunch of marines out screwing around with an ONTOS happened to pull up right next to him and kill him with the backblast.
In the jear before I joined to the army had been an accident with that gun. The load gunner rattled his sermon about loadet, desecured, dangerous area free, ready, and the aim gunner fired. 6yards behind the gun, in the lethal triangle, was a recruit. After the shot the head, still in the helmet and with the ear protectors on, was in safety distance of 30 yards and somewhere between the torso and the separate legs. A second chance isn't in such a situation.
When I was a kid, the G.I.Joe Jeep with the recoilless rifle, was the most expensive add on. I never knew anyone who had one.
“Be nowhere near the back of this gun, ok let’s shot it “ next thing you see a pickup truck slightly sideways the back of the gun haha , Ian its the number one ! I grew up seeing these rifles along other artillery since
My father was an army officer, I remember being 6-7 years and head straight the gun storage to play with them , traverse elevation and breech operation, what a time
I serviced the M8C spotting barrel as part of my final exam as a fitter armourer. Thanks for the memories
8:44 that is one of the coolest shots (no pun intended) i've ever seen in this channel.
I love how after firing the first round, the only thing anyone can think of to say is "Holy shit!". Absolutely tremendous blast wave from both sides of this beast.
Ian, how about a video on how Hamilton and Sons and Drive Tanks go about reloading these large caliber rounds? Curious about what types of powder they use, the priming, and where they come by the projectiles.
Essentially a 450 caliber, 10x a 1911. I'll stand by the breech, feel the flash and reload all day. Spent shell only gets hot if you are slow.
That high speed shot reminds me of every sci fi movie where something happens and all the little stones on the ground slowly levitate to add dramatic effect.
Try sitting in the gunner's seat with your Brain Housing Group right between the muzzle and the breech of that thing. Hello, tinnitus.
that was awesome at 8:46 i've seen alot of high speed firearm shots. many on this channel, but that one was the best. it was only a sec or 2, but you can see the shell spinning with the smoke twisting behind it. most of the time the shell is just a streak, and that all you see. not that time. that was awesome
First saw it used at Fort Polk Louisiana about 1975. They had it mounted to a jeep, standard mounting at the time. It would fire a huge 106mm round down range. The man pack 90mm was used with Infantry up into the end of the seventies. Unlike the 90mm this big 106mm fired at a range of up to 2kms. It used a 50Cal in a barrel along the type. Once the 50 cal tracer, hit you knew your were dead on...then the big kaboom and flash. Later our Anti Tank Platoon had this mounted onto the top of a M113 APC.. good idea because when mounted to a jeep it would tend to be severely top heavy and often men flipped them and injuries ensued. Down side to the 106mm, it made a huge signature, noise and dust at the point of firing...dead give away to the T-62 and you could be sure you gathered lots of attention. So fired in pairs against a lead tank, very effective... survivability??? well.... you got one tank... Ha ha! Later in Korea we were issued TOW anti Tank Weapon in anti Armor Sections. TOW: Tube launched, Optically sighted, Wire guided. TOW's max range was high classified, but easily a 2km bad News post card for Korean T-55s of the time. It was lethal, but TOW clearly solved many of the problems of the 106mm...
6:10 "Don't get them mixed up." Sage advice.
I worked with a Cav unit in 1968 and several of their M113s had those mounted on them.
I wish i could see, even in video, the m50 ontos firing all six of its 106mm at once.
Someone described it as sounding like God is farting into a megaphone.
@UCQDXeBcBtYEzDh7PlBHmbYA If Wikipedia is to be believed, it totally is possible and it leads to spectacular results:
> The [Ontos] was taken to the Aberdeen Proving Ground where single rifles had been tested earlier. When all six weapons were fired at once, the back blast from the firing knocked bricks out of a nearby building and knocked the rear windows out of several cars.
Can you fire a full broadside from an Ontos without rolling it over?
The Iowa class battleships reportedly were recommended to fire a full broadside at once because of this effect
@Shawn Miller You know they are called recoil-LESS rifles for a reason, right? ;)
@@MPI1000 Haha beat me!
I remember being at a fire power demonstration held by the National Guard in the early 1970s; they set up a pile of wooden ammo crates a few yards out behind the gun. The target was a tank hull with turret about 400 yards down range. They fired the round after checking with the .50 cal spotting rifle first. When the shell hit the tank, fire shot out of every opening on it. The back blast was incredible, when it cleared, all the ammo crates were simply gone and a team went over and put out a couple small ground fires. Amazing stuff.
“If it did that much on our side, imagine how much it to the other side!”
I was trained on the 106 in SFQC in 1988. I believe it still may be taught (and fired) there. In 1989, I gave instruction on these weapons to the Honduran army, who mounted them in their jeeps.
"They're dangerous at both ends and crafty in the middle" - Sherlock Holmes
Outstanding! 106 RR was my MOS in the army. Standing next to the breech is a very intense experience. The ones that we used had a 50 cal tracer on it. Once you fire it you gotta move that jeep because there is no hiding where the round was fired from. GREAT VIDEO!!! Why you boys standing so far away when your firing it? Lolololololol! The loader had to stand right beside the breech. It's an experience you won't soon forget!

That ring you hear after it fires, beautiful
I love how ya could see the projectile in the slo-mo footage. It looks like a football with thin smoke trails showing how it spins.
Thanks for the video. In the 60's my MOS was 112 heavy weapons which included 4.2 mortar and the 106 recoilless I remember having to stand beside the breach at attention when the 106 was fired during training. I feel it wasn't the 106 that did in my hearing but the crack of the 50 cal. when sighting in for use.
Again thanks for the memories
That backblast is insane. I've heard of artillery crew members getting smacked by the action recoiling backwards on standard artillery, but this is a whole different ball game.
While attending Officer's Candidate School (OCS) each student was able to aim the spotting rifle to get-on-target and then fire a round. Lots of fun, but loud with minimal ear protection of those times (1962). It is impressive to see the .50 cal rounds traveling to target, and then watch the 106mm round follow on the same trajectory, but slightly 'slower' than the .50 cal round. The tank HEAT rounds look like flying cantaloupes going down range ... :)
I remember going to work with my father in the early 70's at the Corpus Christi National Guard armory and playing with the M40's mounted on Jeeps. They did have the spotting rifles on them. They looked like a couple of tubes welded together. Good times.
Actually they look like a bigger M3 grease gun. I was in that unit, HHC 2nd Bn 141st Inf, from about 1979 til I transferred to the State NG HQ to work in the Small Arms Readiness Training Section as the Operations NCO there. Prior to that I was a 106mmRR gunner at Ft Hoodlum and a TOW II gunner in Germany.
When I was in a Marine Corps infantry battalion in the early 1970s, the weapons platoon had these things mounted on mules as our anti-tank guns. It must have taken real courage to fire one of these things at a tank knowing that if you missed, well, I'll leave that unsaid. I never saw one fired, so thanks Ian for filling that gap in my experience.
M50 Ontos video Ian!! You mentioned it now you have to!!
They have one on display at Rock Island Arsenal the military base. They let you right on the grounds if you are a tourist.

This is great. My Dad used to operate one of these in the Marine Corps and told me stories about it, but this the first time I've actually seen one in operation.
We used to have these mounted on landrovers.
I know where there are a couple of spotter .50s. Not sure about their operational state, though..

9:15 Interesting to see how the exhaust gasses kinda go bloop-bloop-bloop-bloop... at the muzzle end.
I have an M38A1C, which is the converted M38A1 Jeep to carry this weapon. (The later Ford M151, which was used extensively in Vietnam also had heavy modifications.) The conversion for the M38A1 to M38A1C was: "Remove rear seat, discard" which always made me chuckle. Cutting out the back of the body, and welding in angle iron to support it. The windshield was changed out to one with a slot in the front for the barrel. Installation of a barrel mounting clamp on the dash, to hold the barrel while in transit. And there was a conversion of installing coil-over springs in addition to the leaf springs in the rear, the kit installed brackets on the frame (some drilling required), and brackets on the axle, which housed the springs to support the additional 575 pound weapon. Other smaller notes were that the "open" shackles were changed to "close" shackles on all 4 leaf springs, and the installation of ammo racks in the back floor. Additionally, the kit included mounts to change the position of the jerry can and spare tire to the sides of the vehicle - however these were not always installed. I suspect to save on weight. Because this vehicle got heavy with all of the modifications. I could still get up to 50mph+ on flat level smooth roads, but going uphill on modern freeways and highways getting bogged down to 25mph or less is frankly dangerous.
Wife: Why did you buy this? *points to M40*
Me: home Defense.
I was in D Troop, the ground troop, of 8/1 Air Cav Squadron at Ft Knox in the early 70's, and every platoon had one of these mounted on a jeep (with a modified windshield so the barrel could be stored facing forward), a 5/4 truck with a mortar (plus the platoon Sgt), and a bunch of jeeps with M60's on pintle mounts.
Every now and then we set one up for a demo for the officers going through the Armor School, stack a bunch of wooden ammo boxes behind it, and fired it off.
It turned out to be really, really good at making toothpicks.
Crazy that the M50 Ontos had 6 of these strapped to it
My grandfather was a U.S. Marine in Vietnam and used to talk about these things, I even found some of his paperwork once. Thank you Ian for finding and shooting one!
Huh! That's a curious coincidence. I just watched a video last night about the M50 Ontos, which mounts 6 of these things!
PT's Sleepy Corner Could you imagine having a modernized version of the Ontos in Iraq after the last invasion?
The same six M40’s, lasted designators for the weapon have been around for years to replace the spotting rifle, maybe a couple HMG’s for gunfire support too.
Modern diesel power plant, maybe use that flexible rubber track you see on a lot of farm tractors instead of a the usual metal linked tracked
Matsimus?
@Stuart Kirk
Probably.
Same story for me...
The Marine Corps unit that I was with Second Battalion Fourth Marines,Based out of Camp Foster Okinawa Japan in 1977 .Had these guns And had M-274 Mules to mount them on. As well as the mount shown in the video . I got to move them around as well as all the ammunition . in the M-561 Gamma Goat I was assigned .They were quite a site to see .
It's insane that a weapon like this was the best solution to a problem at one point
I'm here after watching the M8C video. Now we just need to see both the M40 with the M8C on it.
And O By The Way - while it is safe to stand to the flank of a recoilless rifle, and quite close to it, there is a "sweet spot" a few paces to the flank of the barrel mid-point, where the shockwaves of muzzle blast and back blast meet.
It is THE place to stand your ear-muffed spectators, if you want to see them stunned and floored by the combined impacts, Equally, it's a bad place to site your Jeep/ 4 x 4 if you like the windshield to stay in one piece and where its designers placed. Same applies to the shape of the exterior body panels.
Trust me on this.
Trained on the 106 in the SADF in '86 and '87. Brings back memories. When you fired the sucker it felt like you got punched HARD through the face! Not a good idea to shoot with a hangover.
Davy Crockett, when?
BWHAHAHAHAHAHAHAHAHAHAHAHA! Davy Crockett! I actually know what that is! BWHAHAHAHAHAHAHAHAHAHAHAHA!
Did the army ever have the nerve to touch one of those off?
I seem to recall watching a documentary that mentioned the Davy Crocket was only ever test fired once.
I had the pleasure of firing this weapon many times and it was GLORIOUS!!
My grandfather crewed one of these when he was in the reserves, they carried it on a jeep and his had a ranging rifle.
Like mine
I was in the infantry in Germany in the mid-60s, and our unit had these... All ours were Jeep-mounted. Pretty spectacular to watch...
We also had the shoulder-fired 90mm RR.
2 years later he found that 50
Loved that thing. I was a 106 RR Platoon Warrant in the 80’s with the Canadian Military Reserve.
The Ontos wasn’t a “repurposed” tank, it was designed from the outset to carry 6 of these weapons as an anti-tank vehicle, a lot of people claim it found its true purpose as an anti-personnel weapon during the Vietnam war.
Its moment in the spotlight was during the street fighting at Hue.
... ANTI PERSONNEL!! What kind of personnel warrant 6 of these cannons! Gotta make sure that insurgent with a run-down ak is definitely dead
@@spysareamyth Hey when you got 50,000 screaming Charlies coming at your position you would want to be pointing a bunch of these bad boys at them to ya know.
Purge Blade #231 Look up a round called the Beehive Anti-Personnel Round, a 105mm round packed with flechettes, that was used in Vietnam, imagine 6 of those rounds fired into an area at the same moment, that would be about as anti a person as a round could get.
@@spysareamyth The NVA were not known for employing armor, and you use what you have. True purpose is debatable. Used to good effect in a secondary role is probably the most balanced way to state it.
Also, he said repurposed tank chassis, which is different from repurposed tank. I do not know it it's true either way, but it is different. USPS city mail LLVs(Long Life Vehicle - the small boxy mail trucks you've probably looked at and not seen hundreds of times) are, or at least were, built on a Chevy S10 chassis, but no one would call them repurposed S10s.

I always thought the M50 Ontos was the second-least-appreciated armored vehicle after the M113 ACAV. Lighter and cheaper than a tank, but with a hell of a punch.
But some unfortunate soul had to get out and reload it.
@@gunmnky That just gives you an excuse to get the whole thing behind cover before someone blows you up. "Well, gotta reload, no need to stay in the line of fire!"
And it still beats the hell out of the Sheridan deathtrap. When the crews would rather sit on the _outside_ of the tank than the inside, you seriously screwed up your design.
I qualified with the 106 mounted on a jeep with a 50 cal spotter, when in dought pull out for the 50 and push for the 106 ,the concept for this weapon was a hit and run mission like the man said once fired the enemy knows where you are hence hit and run
"Kissed by GOD"
you feel all warm an fuzzy inside when shooting a recoilless 😍
Good description of this weapon system. I was a Ski Patrolman at Alta. UT and a Forest Service Snow Ranger in Big and Little Cottonwood canyons for two decades. Over those years I spent many many gun crew missions on the 105 and 106 recoilless. I also got to shoot 75 recoilless and pack howitzers. What a great experience doing avalanche mitigation with these weapon systems. Dave
It's good that they got to be used for something other than their intended prpose.
G'day nice big boom stick you've got there
@@davidabest7195 Isn't that why it was designed to be easily removed from the stand?
David Abest it has no recoil. U should be fine 😂😂
About 1981, My employment was to help finish and assemble the 106mm recoilers rifles. We also manufactured the barrels, breech blocks, and the main chamber. We were especially careful to deburr the firing pin and its hole to insure that the firing pin could not hang up as it was extremely dangerous to open the breech block with a stuck firing pin. I learned a lot about the M40, but was never able to fire one. I wish I still had the original manufacturing drawings.
