The field dressing (bandage) is part of the standard equipment of every soldier and can be used when you or your teammate is bleeding. Every soldier has two bandages to apply except medics who have five. Apply to yourself by selecting the field dressing and holding right-mouse button. Apply to teammates by selecting the field dressing and holding left-mouse button. If you run out of bandages you can resupply at an ammo crate in FOB's or at the main base.
