I find that terrorists can take out a Tomahawk, and the Tomahawks can't destroy them, as they don't track infantry. He'd have to then incorporate infantry defense into his force. Another good way is to use Jarmen Kell to "borrow" his Tomahawks.
Thanks for the tips.
You should be able to rush and kill him before he is able to get a strategy center up. Use RPGTech rush on his supplies; try to take down the chinooks. If you can after you kill the chinooks load up and look for another undefended spot or take them back to your base for future use. Attack early with this right after the rush ASAP. Build up about three RPG filled techs with a worker in each one and try to build some tunnels in his base. This also gives you 6 more RPG men and anti-infantry fire. Then build a barracks and make terrorist, RPG men, and rebels with capture building. If this doesn't kill him the build a palace and start making rocket buggies. Use these to go in attack and retreat. They should be able to kill anything that approches and still be able to get away. When you rushing at the beginning make sure you still build a second supply center and keep making units. You should also sell your command center as it gives you 1000 more money at an important time. You can rebuild it later in the game when you have plenty of money. Build you first tech then the radar van so you can be on your way as fast as possible. Don't play defensively with the GLA. ALWAYS be attacking his weak points. Try to use multi prong attacks to devide his forces. Also use this to have an attack force act as a diversion so you can come in another way and level a few buildings.
If you're into early rushes, just try three Quad Cannons. They can destroy most buildings very quickly. Also, they can destroy any infantry and even Chinnooks. Your main objective should be to keep USA from building up to all those Tomahawks. USA almost always wins long games like that.
use rocket buggies with ammo upgrade @ the black market and if he sends guys after them then retreat them into a tunnel. if there is an airforce, bring along quads. tbh vs usa it shud never get late game. vs all usas especially laser, tech spam from 2 arms dealers/ 2 supplies usually owns another rush is quad / rpg. usually starts @ 2 quads and 6 rpgs from tunnels vs usaf though, the rpgs are useless so just quad spam and that works well until the enemy gets search and destroy, and if usaf gets a strat center up ur a noob and screwed
I'd agree mostly with LtSmash, but the reason why I didn't say to use Rocket Buggies is because they can be destroyed by one Tomahawk missile, so unless you keep them very close to the Tunnel Networks, you're going to lose them quickly.
since your losing late game but you can hold him off otherwise I think you should be the demo general and use sneak attack with the demo upgrade to take out his tech/airfields
