You can disguise yourself from the enemy by using their vehicle, but you cover will be blown if you hang around too long, kill enemies using the vehicle armaments, or hit them with the vehicle. However, enemies do not seem to mind being killed after being hit by vehicles hanging from the winch cable of a rapidly descending helicopter or vehicles released from the winch cable to be dropped on their heads from above. Also, enemies do not seem to mind when one of their helicopters arrives and repositions all of the nearby fuel tanks to strategic locations, such as reinforcement bunkers, alarm towers, guard towers, destruction target buildings, enemy armor, etc. Even more, enemies do not seem to mind when the helicopter drops exploding barrels, jeeps, trucks, tanks, etc. down onto the strategically placed fuel tanks. You can perform HVT captures with ease by eliminating the ground personnel from the air, then land and claim your HVT. You can perform target destruction by placing a fuel tank on top of the building, then dropping something explosive on the fuel tank. If you have the time, and like keeping your factions friendly to you, scope out what faction you are going after, get one of their helicopters, and have fun. The only difficult part is finding a fuel tank. Sometimes, you will have access to more than you need and other times you will have to travel far to find one.
