1: Add armor to tanks so if a rocket hits it it can either reflect the rocket, or pierce it, and the weaker the weapon used, the less damage it will likely do, also add a javelin type weapon where you can lock onto a tank, and to counter their could be a little launcher that serves like flares for the tank to launch and avoid being hit, it could have a cooldown of 30-45 seconds. 2: add a jungle map and naval warfare mode with submarines and destroyers and stuff.
