-Line an area with a sequence of Patriot, then Firestorm Base, Patriot, and keep going. After that, fill the Firestorm Bases with four Pathfinders. This will help you take out infantry without the trouble of Flashbangs or other hazards.
-Get a Combat Chinook and fill it bothPathfinders and Rocket Launcher troops. If you are facing several tanks, go with more Rockets. If you are just cleaning up infantry, get more Snipers. A combination of two Snipers and six Rocket Launchers is excellent for clearing occupied civilian buildings (for example, the Laser General level in Generals Challenge). Just hover by the building and the Rocket Launchers can open fire. When the enemy soldiers are flushed out, the snipers will pick them off immediately. This can also take out tanks better than Commanches, because the Rockets reload fast. However, Gatling Tanks can take these down very easily.
-Build four Patriot Missiles and two Firebases (artillery centers). Inside each of the Firebases put a Sniper, two rockets, and a machine gunner This will tear your enemy's assault vehicles and infantry to pieces very quickly.
