Where the Militia Arms Depot is
A battered residential district of apartments and narrow shopping streets south of Wolves Stadium, bounded by the south fork of the Hajin River and home to Compound Echo.
The report places the Militia Arms Depot door in Hajin River Heights at grid G7: the lower-floor armory in Gangbyeon Apartment B at the Hajin River Heights compound. Our MW4 DMZ map marks Hajin River Heights itself, not this door, because the door has not been confirmed. Our grid overlay is approximate, and some reported grids fall outside it, so trust the grid printed on the key in your backpack.
Before you go to Hajin River Heights
- Hajin River Heights is rated up to Medium threat by Activision. A duo or a careful solo run is realistic, but expect other squads drawn to the same loot.
- Compound Echo is a converted apartment block near the river: expect a fortified fight.
- The comms tower on South Island is a landmark in the south.
