What we know about the Commandant Office

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.
