Bunkers are permanent location on the Global Map.
Each bunker is identified by a name from the ICAO phonetic alphabet. These locations can be accessed (by foot or only by vehicle) but require CAC Cards upon arrival to get inside and an access passcode to unlock the lift to lower levels. This passcode changes every two days and can be found on a Dead Soldier or obtained by checking one's CB Radio at their base.
