The Militia Arms Depot in MW4 DMZ is a helpful place for players wanting to acquire valuable loot. However, in order to get into that room, you need a key. If you don’t have the Gangbyeon Apartment B key, there is an alternative method to get the key and to open the depot.
How to Find the Militia Arms Depot Key


Follow the location marked on the map above. In the case of not having the Gangbyeon Apartment B key, position a car near the nearby structures and use it to climb onto them. Moving up halfway to the building, shift left to locate the window on the side, and get inside the apartment. Finally, search the inside of the apartment to find the key.
If you can’t find the key here, then it is probably a random drop. You need to check every loot crate and supply chest that you come across to find it. The easiest way to do that is to complete orders and missions to explore different locations to locate loot crates. If you still can’t find the key, then you should team up with players who have it and join them on finding the door too.
How to Enter the Militia Arms Depot

Once you have acquired the key, you need to go back to the entrance of the depot and unlock the door. You will then be able to go inside and take the valuables. Be careful when you walk up to this place since you may be spotted by a drone or there may be other enemies nearby. The depot is said to contain good loot, making it worth exploring if you can access the room.
