Hoesik Supply Room is an Epic key in MW4 DMZ. It opens a military supply closet in the office block at the Rice Mill in Imjin Farmland, grid D8. It is easy to search the mill itself for this door, but it is upstairs in the white building next to it. Below is where the door is, how to get there and what we found inside.
- The door is upstairs in the white office block with the blue stripe at the Rice Mill (D8), not in the mill building.
- Ground floor door, wooden stairs up, then the door with the Storage sign.
- The Rice Mill was a Medium threat area in our run.
- Seven containers with an Impact Warhead recipe, two Degraded Execution Footage, cash and five rifles.
Where the Hoesik Supply Room Door Is
The Hoesik Supply Room is in the southernmost office building at the Rice Mill in Imjin Farmland, grid D8. That is the white two-storey block with a blue stripe along the front, next to the mill and not inside it. The door is on the upper floor, a plain door with a Storage sign next to it. The Rice Mill was a Medium threat area in our run. You can also find the door under the keys layer on our interactive MW4 DMZ map.

How to Get the Hoesik Supply Room Key
The Hoesik Supply Room key is field loot, so it can drop from ordinary containers on Hajin. We do not know of a fixed spawn for it. Every other key and the door it opens is in our MW4 DMZ keys guide.
The Route to the Door
- At the Rice Mill, find the white office block with the blue stripe on its south side.
- Go in through the door on the ground floor and take the wooden stairs up.
- At the top, follow the corridor to the door with the Storage sign. That is the Hoesik Supply Room.
What Is Inside the Hoesik Supply Room
The supply room is a green-lit storage room with shelves, desks and a row of lockers. We opened seven containers, a weapons locker, a rifle case, two safes, a green weapons cabinet that the game calls a Cache and two military lockers. A Nylon Laminate lay loose on a shelf near the door.

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
Our best find was an Impact Warhead recipe in the Cache, worth $5,000. The two safes and the rifle case gave two sets of Degraded Execution Footage, Infantry Invasion Plans, Regional Combat Notes and $2,000 in cash. The room is also full of rifles, with two Mosin-Nagants, a Warlord, a KG-7 Vulcan and an Oris 8.6, plus a Recon Drone and a Medium Backpack in the lockers.

Is the Hoesik Supply Room Key Worth It?
Yes. It is a small room with two safes and a weapons locker, and it is very easy to get to. There are no fourteen floors of stairs here, you are at the door within about ten seconds of reaching the office block. Loot is random, so not every run will be spectacular, but two safes and a weapons locker can give you some very good stuff. The Imjin Mill Foreman’s Office at the Rice Mill is a short walk away if you carry that key too.
