Here's an idea: Eveyone in the squad carries a healing-device-reload-thingy. The medic carries several.
The situation: You're dead.
The medic comes over, loots your body of the healing reload, and brings you back, and patches you up as best he can with whatever's left of your reload.
The medic's own reloads can be used to heal people in a fight, when you don't have time to pass inventory around.
Same tactic could apply to armor-repair-thingy reloads and engineers, but would be less critical.
This may be a moot point if the MAX can carry so much that ammo becomes a non-issue. But I don't think it will. And the MAX bloody well better carry an armor reload... I get the feeling they'll need it.
This may not work if the reloads of either type are too big.
Time will tell.
