do you think it is a little gamey to have your tracks / engine / turret / ammo loadout instantly repaired with a click of the mouse?
Planes don't get em so why should Vehicles?
Because planes didn't have ammo carriers that moved up with the units. THEY HAD TO FLY BACK TO BASE TO REARM AND REFUEL. GV's typicaly were refueled when needed (just behind the lines if need be, you die if you run outa gas during an attack). And what do you think they did when low on ammo? Did they return to the motor pool? Nope.
