What we know about the Field Depot
- DMZ Codex says the door is behind an Ammo Armor Cache in the first-floor maintenance area, with FIELD DEPOT on the lock.
- The two sources disagree on rarity (Dexerto: Epic, DMZ Codex: Rare), so we do not give one.
- The Weapons Mod Workshop and the Air Base armory use different keys.
How to reach it
Read the grid on the key’s own description first, then type it into the MW4 DMZ map grid search. Our grid overlay is still approximate, so use it to get to the right part of Chang-san Air Base and then look for the building named above. The Chang-san Air Base page lists its threat levels and named zones.
