first build your supply trash then your barracks.when your supply trash is ready build two armsdealers,quikly build two combat cickels and get two workers on each one of them
then send them back to the enemy's base cickels can climb cliffs go on and build two tunnel networks you must already have your tanks and quad cannons built.send them in to the tunnels and attack from the back of your enemy's base you should win with this strategy every time.

One GLA rush tactic that makes the filthy Americans angry is the tunnel rush: Send the first 2 or 3 workers you build immediately towards your enemy's base.

The next workers that come out of your command centre should start building a barracks and supply stash and other buildings as per normal.

By the time your first workers arrive at the American base your barracks should be finished or nearly finished. Get the workers to start building tunnel networks near the American buildings. The Americans may kill a worker or two but at least one sould ne able to finish building.

The tunnel network gun will shoot anything that comes out of the buildings and the 2 rocket soldiers can shoot up the enemy dozers and chinooks. This works especially well with the toxin tunnels.

Build a tunnel network in your own base so that later when you have an arms dealer you can build quad canons and rush them through the tunnels to the enemy base and finish it off the American cowards. Surviving workers in the enemy base can also build demo traps and other things to hinder them.

Create your defenses... dont just stick with your stinger sites... use the palace and put rocket infantry inside. The good thing about it is its tougher than most buildings. Next use tuneel networks to transport your forces in every place in the map. Use the camo upgrade to hide your stingers and tunnel networks. Use Quad cannons for aircraft and infantry. For assaulting an opponent, use the rocket buggy. Their fast, deadly and has a good range.

When you use the sneak attack upgrade be sure that you have forces ready to get inside the tunnel, use this ability together with the rebel ambush but use it away from the tunnel network, capture or target buildings to confuse your enemy.

Build a lot of black markets to generate income, a lot of arms dealers to generate a large force to attack the enemy since GLA has weak armor.

Good thing about the demo general is the rebel ambush. Target it near buildings and let them attack it, the enemy will respond by killing the threat but the rebels will blow up once their killed, this does not work with pathfinders.

The GPS scrambler of the stealth general is very useful for hiding buggys so that you can have a stealth rocket buggy.

Use Scud Storms for massed units near buildings. And then use your sneak attack and rebel ambush.
