I haven't seen this question come up but I'm confused about how a character hold inventory during a mission - e.g. Qiang Gao is wearing full armor and using a weapon in both hands. If he opens a loot box with three loot cards, can he only put two in his empty backpack slots and give the third to his teammate or throw it away? I notice that automedikits with character portraits don't take up backpack space. Are there other equipments that don't use up backpack space?
