^^little 1idea:>
~~ all vehicles (not only cars and APCs) would be as actively playable, - driving and fighting in battles (on tactical map), - yes
.. - yep, ~ exactly like an APC´, carriers, and attack hellicopter also (in role of) as transporting units in C&C, Command and Conquer series
so, such land vehicles would be heavier armed with any bigger guns, and,/or rapid-fire (twin) cannons, /some rockets, /missiles, /tank-flamenthrowers, etc..
(and any machineguns too, minimal ~12,7
or gatling, GAU'; ~~25~30mm
..if yu, the team got a APC, / MBTank in garage, hangar, - why would not use it to its full potential, and possibilities? ?
