Command & Conquer Generals: Zero Hour Hard - GLA Campaign - Mission 5

Freeing the PoWs ASAP is a priority, being attacked by only one enemy, albeit the main threat of the level is better than two.
Plus the $10,000 you get when the PoWs reach their base is nice too.
Helix work rather nicely for this level, and a few SCUD storms too.
An argument could also be made for Overlords via Sneak Attack, or even mass Commanches.
Make sure you nab all the UN cash crates with your bike to begin with.
Jarmen Kell in a Helix is pretty nice along side Rocket Soldiers.
Quad Cannons will be your main defence, and maybe a few Stingers or Patriot Missiles if you wish.
One thing to try and do is leave the Strategy Centre alone and capture after (or during) building your own. This will allow you to employ two boosts to all of your units (I'm not sure if you can do the same twice to stack it). Most of their Power is exposed, and Super Weaponing it leaves only a few Power Plants needed to be destroyed too.
Avengers will be your priority if employing a Helix based strategy as they will tear you down the quickest. they do seem to have a lot of Dozers to replace lost structures and two Command Centres close to each other that you should take out next. Next up the War Factories followed by the Air Fields (or the other way round if your base has taken a pounding). Finally mop everything up.
Be aware of the expansion they try to set up by the SE entrance to their base in the village.
I waste time taking out defences towards the end, when I just needed to take out the Power. I think you don't even need to take out the Particle Cannons if there are no power plants or production structures left, as they are rendered useless (I know this is true in Generals Challenge mode).

The POWs will be stealth with the Camouflage upgrade

May I ask, what happened when the POW timer runs out?

Pretty sure it starts the script for the US base to start producing units to attack you with. So you face two enemies.
