This is precisely what I want to do once Fallen Earth (mmo.fps.rpg) comes out.
I'd love to ride shotgun with a heavily armed convoy of Enforcers making supply runs from town to town. Perhaps we'll trade Tech supplies or stolen goods?
The point vehicle of choice would be a heavily modified "Shilka" AA tank (with a modified radar so it picks up ground targets as opposed to airborne ones). It's the apocalypse, so I can't exactly be picky
. Maybe a super hind for aerial support and additional transportation.
That, and stopping other faction's convoys dead in their tracks with our heavy sniper rifles while my pals race in to mop up on skirmish buggies!! (I suppose we can't use the AA guns nor the 30mm on the Hind because we want to minimise collateral damage.)
I guess that makes us a heavily armed raider convoy then!
