Command & Conquer: Generals: Zero Hour

Command & Conquer: Generals: Zero Hour cheat codes: 
Get those USA slow units to the battle faster:
Most battles need support eventually and if you need a slow but
powerful unit to get from your base to the battle on the other
side of the map, use your Chinooks. A single Chinook can carry
up to 2 vehicles like the tomahawk missile, though some for some
units you can only fit one in a Chinook. But its a quick way to
keep the fight going and get that one unit were it needs to be
to win.

US defense strategy:
Build four patriot missiles and two firebases (Artillery center)
inside each of the firebases put a sniper tw rockets and a machine
gunner This will tear your enemies assault vehicles and infantry to
pieces very quickly.
