It'd be neat to have some heavier duty vehicles of a military flavor to use in the world. Mainly the Humvee and the M2 Bradley (could throw in the JLTV if you're feelin fancy) would be plenty. You could include all the parts and maintenance for the vehicles as well as limited ammo for the high powered stuff. Or add a station to craft ammo that as you level up work your way up in tiers until you get to the military tier and replace the spent ammo. Would be useful too for PVP in multiplayer.
