Should add vehicle upgrades like more armour, faster, and MG upgrades like suppressor scope or AP rounds that do more damage to vehicles but less to infantry. this should be accomplished by kills with vehicles or "ride time; the time you spend in the vehicle. also should add tire popping or if you hit a MG on a vehicle or damage it enough it has to be repaired or take time to come back, also make it where if you keep you vehicle at HQ long enough it gets slowly repaired.
