How air gets to the tires in a Central Tire Inflation System (CTIS) - M44A3 Family of Trucks

I am a longtime military vehicle enthusiast and own a 1995 AM General M35A3. These vehicles and others like it have provided soldiers all over the world with a means of transporting food, ammunition, medical supplies, and other soldiers during peacetime, war, and disaster rescue operations. I enjoy this hobby not just for the cool military trucks, but also to preserve military history.
This video shows how a Central Tire Inflation System (CTIS) moves air between the truck and its tires. All CTIS work similarly. The difference with the M44A3 family of trucks is that recycled M44/M45 axles had the CTIS capability adapted to them instead of being designed to accommodate CTIS from the start.
About the M44A3 family of trucks:
The M44A3 family of 2 1/2-ton trucks (deuce-and-a-half trucks) were made in accordance with the Extended Service Program (ESP), which recycled M44 and M45A2 truck frames, driveline components, and sheet metal and added some modern military truck features, such as a CTIS, Caterpillar 3116 diesel engine, Allison 1545 4-speed automatic transmission, super single tires, cab heater, air dryer, and reverse lights, among other things. The ESP was developed to address concerns that the new-at-the-time Light Medium Tactical Vehicle (LMTV) wasn't going to be delivered to Army National Guard and Reserve units on schedule.
The M44A3 family of trucks included the M35A3 cargo truck, M35A3C dropside cargo truck, M36A3 extra-long wheelbase cargo truck, and the M109A4 shop van. About 6000 trucks across the four models were built by AM General between 1995 and 1998. These trucks were built at two-thirds of the cost of the LMTV.
