Any time I’ve been in a RPG campaign in which significant vehicle combat was involved, I opted or urged for the use of any vehicle combat game to handle it, if that were an option. So wargames like Star Fleet Battles, Starfire, Car Wars, Battletech, Crimson Skies, OGRE/G.E.V. and others were always on hand.There is no RPG that has vehicle combat that is fun to play out.
I sometimes do likewise when doing the mass combats for battles & wars, like using Federation & Empires for Star Trek fleet battles.
