Bandages are useless. They are what the nurse puts on after you have had your cut, operation or whatever seen too after treatment.
Never in the history of warfare has a bandage saved a life. They are what you put on in aid stations to cover the wound so the patients cannot see their wounds.
You do use field dressings but they are a quick tie around pad. I was never issued bandages when I served, just one field dressing as you don't put one on then start back at it.
This is the most ridiculous part of the game and I would rather see the Wildlands way return than this garbage.
