when you join the battle look at the mini map. try to stay with a group. your attacks and protection are greater if tanks stay close to each other. a single tank will die fast when being attacked by 2 or more enemy tanks. you can be sneaky by attacking from far away or high on a mountan or go after them from behind. on upgrades. get autoloader 1st. its inportant to shoot as fast as you are able to. get upgrades in this order. autoloader. maingun, armor, chassis, engine. if you are being over run, back away and turn. if you after a tank, and can hide behind something. rock back and forth as you make your attacks. the best defense is always a great offence. be aggressive. go after your target fast.
hope this helps some folks.
