They did say that you couldn’t re-supply the same field you spawn from.
As for re-supplying a vehicle, that’s not a biggie, I rarely have run out of ammunition before someone drops a pickle on me. The good thing is that it will repair damage. That is outstanding. I’m thinking though that getting someone to spawn an M3 to repair some GV’s when a base is under attack, lol, not sure it will happen much outside squads.
