I think the GIs are relying more on having a sustained medical response system right behind them, from platoon medic to Walter Reed. I guess for a small independent team, having more stuff right on hand takes on more importance.
If I were going over there, I'd want the kitchen sink, and then some. Chest tubes, oxygen, central lines, crystalloid, plasma, crichothyrotomy kits, and more than just a pair of scissors for surgical instruments. They make a mechanical respirator that's small enough to fit in the palm of your hand. I'll take one of those, too.
