Tracked tanks move far too fast, almost as fast as a quad or a 4x4. This gives them an excessive strategic advantage, especially in terms of mobility and escape.

Helicopters are also too resistant to rocket launchers, which makes combat unbalanced. Countermeasures are understandable, but needing multiple rockets to destroy a helicopter is still excessive.

A possible solution would be to add area damage to helicopters: players close to the impact point of a rocket would be eliminated, then an alarm would trigger inside the helicopter. It would enter a crash state, allowing the remaining players to bail out in an emergency.
