Medics:

Medics are allowed to "heal" players when they are marked on the field, on any part of their bodies or equipment other than faces or heads. Players marked on faces or heads or eliminated by an explosive or other prop may not be healed. Medics may not heal themselves but may heal other medics. A medic has 60 seconds to reach a player who has been marked, unwrap the band-aid, place a band-aid on the hit player’s mask, and wipe the paint from the player. If a player is shot during the course of the game, they can remain for up to 60 seconds and call for a medic to come to his location. A player is not allowed to move from his position when marked. When a medic runs out of band-aids he may no longer heal other players until his general can acquire more. A medic can only use his card until the blanks are filled. If a medic is caught cheating, that army will lose the privilege of that medic, and the player's ID card will be punched.
