The big one lies under Chang-san Air Base: a bunker complex bigger than the base above it, rated Extreme. Its armory opens during Operation Iron Citadel, and the Supreme Leader's blast door at the bottom takes a single-use access card. Silo bunkers stand in the west of Hajin, and the Chemist's room sits behind a bunker door at the reactor.
Where is the bunker in MW4 DMZ?
Under Chang-san Air Base on the west side of Hajin. The base is built into a granite hillside, and the bunker complex below it is bigger than the base itself, with large bunker doors in the hillside to the south and tunnels beneath the terrain.
The surface is rated Critical and the Air Base Bunker Extreme, the highest threat on the map. Commander Colossus has been met down there, and a Hunt Operator Dynamic Op once put its target in the bunker's Control Room.

How do you open the bunker armory?
During Operation Iron Citadel. The Access Card becomes the Armory Card at the upgrade terminal in Admin Complex No. 2. Then go down into the bunker, find the three notes that each hold part of the code and enter the six digits at the armory keypad. The code changes every match.
Inside the armory stands the DRC Weapons Locker, which takes the Air Base DRC Weapons Locker key. Bring that key on an Iron Citadel run, because the armory is very hard to reach outside the mission.
How do you open the Supreme Leader's bunker?
With the Supreme Leader's Bunker Access Card. It opens the big grey blast door with the emblem at the very bottom of the bunker. Operation Iron Citadel rewards one, and Bale drops it as his Lieutenant key, though not often.
The card works once. After that, a Door Breacher Charge is the only way back in, so keep one for this door.
What are the silo bunkers?
Bunkers in the west of Hajin, each with a locked inner door that leads further down below the map and an escape hatch you can open electronically from inside. Our Hajin map shows six of them on its Silo Bunkers layer.
Each one holds a single enemy, a weapons locker, rifle cases, military bags and caches. The front door stays locked, so walk around to the door you can open. Looting all six makes one of the easiest money runs on Hajin; the Bunker Loot Run guide has the route with its map.
Hidden missile bunkers also flank the air base, among the wilderness, hamlets and small supply depots around it.
Is there a bunker at the reactor?
Yes. By the road at the northeast boathouse of Haneul Nuclear Reactor stand two bunker doors side by side. The left one opens freely, and the right one is the Chemist's room, opened by The Chemist's Secure Armory key that the Chemist drops.

LieutenantThe ChemistA Lieutenant in a yellow hazmat suit and a full-face mask, holed up in the warehouse beside the reactor tanks at Haneul Nuclear Reactor, inside the radiation zone. Hazmat guards hold the doorway.
Is there a code for the bunker?
Not a fixed one. The armory code in Iron Citadel is six digits from three notes in the bunker and changes every match, like every keypad code in DMZ. Lists of bunker codes you find online come from the campaign mission Stranded and do nothing in DMZ.
