a lot of ppl use complex tactics that often fail and disappoint. the easiest way that i have found is to be the usa laser general build a lot of laser cannons along your frontlines. do this while you are stepping up your resource gathering. then build supply drop zones a lot of them. building more resource gatherers will just be destroyed and hurt you and you cash flow. as soon as you are able to build particle cannons at least 2 for each of you opponents to take out their superweapons. use caution when playing against china and gla their scuds, rocket buggies, and small nuke carriers can sometimes be out of range. for this always keep a small group of avengers and humvees filled with rocket men. this tactic will put you on top while your opponent struggles with resources.
