Right weapon:
Use the right weapon system for the right job. Helicopters are great tank busters, but are vulnerable to thin-skinned antiair vehicles. Use tanks to clear the antiair vehicles before employing your choppers. The helicopters are also good at popping up from behind ridges (using the Set Helicopter Height option), shooting a couple of missiles, and then diving for cover before the enemy can return fire.
Less capable tanks:
Place your less capable tanks (such as T-72s) on the reverse (that is, opposite) side of the hill from an enemy advance. The enemy won't be able to see the tanks until they crest the hill, and then the T-72s can pour shells into the enemy at close range--hopefully negating any technological advantage the enemy has. That's the theory, but it didn't work too well for the Iraqis at Medina Ridge.
Multiple weapons:
Use your weapons' different ranges to set "kill zones." Deploy TOW Antitank Guided Missiles to the rear, place tanks a bit forward, sprinkle the area where you wish to engage the enemy with mines, and then let loose when the enemy arrives. It is the synergy of multiple weapon systems simultaneously engaging the enemy that wins battles.
Knowledge is power:
Use your recon vehicles to probe enemy positions, then engage the opposition with your heavy armor.
