Five bags, each unpacked from ACE self-interact:

• Unpack Boo Boo Bag - anyone; the everyday kit every rifleman carries.
• Unpack Medic Bag - Combat Lifesavers and up.
• Unpack Trauma Kit, Fluid Kit, Drug Kit - Medics.

What goes where follows the fill order: backpack, then vest, then uniform; what does not fit lands on the ground. None of it works on the map, unconscious or captive. ACE interact on an unconscious casualty: Take Medical Bags.
