Found a Hoesik Supply Room Key in your inventory and have no idea where it goes? You’re not alone.

This guide covers the exact location, how to navigate to the door, and what you can expect inside once it’s open.
What Is the Hoesik Supply Room Key in MW4 DMZ?
The Hoesik Supply Room Key is an Epic rarity key in Modern Warfare 4 DMZ. It unlocks a military supply closet hidden inside one of the buildings at the Rice Mill POI in Imjin Farmland. Like most keys in DMZ, it’s a single-use item โ the moment you open the door, the key is gone.
Epic keys generally open some of the better locked rooms in Hajin, and this one is no exception. The room holds multiple loot sources packed into a small space, which makes it worth the trip whenever you happen to hold this key.

Hoesik Supply Room Location in MW4 DMZ
The Hoesik Supply Room is located at the Rice Mill in the southeast corner of Imjin Farmland. On the Tac-Map, you’re looking at roughly grid square D8.
Imjin Farmland is one of the calmer POIs in Hajin. It doesn’t draw the heavy PvP traffic that places like The Grid or Chang-San Air Base tend to attract, so you can usually work through this area without running into rival squads. AI hostiles are present but manageable if you approach smart.
How to Get to the Hoesik Supply Room Door
Once you land near the Rice Mill, don’t head into the main mill building itself. That’s not where you need to go. The locked room is in a separate, smaller office building on the southern edge of the Rice Mill complex.

Here’s exactly how to reach it:
- Drop into Imjin Farmland and head toward the Rice Mill.
- Look for the southernmost office building โ the smaller one at the edge of the compound, not the main mill.
- There’s a Bounty Station nearby which helps you find the right structure.
- Enter the building and go up the stairs to the first floor.
- Look for the brown single door next to a pale-blue wall.
- The interact prompt will read HOESIK SUPPLY ROOM when you’re at the right spot.
- Use the key and the door opens โ the key is consumed at this point.

Make sure you’re ready to loot before you unlock it. There’s no going back once that key is spent.
What Loot Is Inside the Hoesik Supply Room?
The Hoesik Supply Room is a solid loot stop. Inside you’ll find:
- Weapons Locker โ contains contraband weapons or Gunsmith builds
- Safe โ has been recorded dropping items like Infantry Invasion Plans and other high-value documents
- Cache โ standard loot container with materials and gear
- Epic Materials โ useful for 3D Printer crafting back at your FOB
- Cash โ always handy for buying loadouts or trading at the Buy Station
Loot contents change each match so what you get isn’t guaranteed, but the combination of a safe, a weapons locker, and a cache in one small room makes this one of the more rewarding Epic key locations in the Imjin Farmland area.
If you’re actively farming ingredients for crafting, the Epic Materials here can save you time. Learn what to craft with them in our MW4 DMZ 3D Printer recipes guide.
How to Get the Hoesik Supply Room Key
There’s no fixed location or guaranteed drop for this key. The Hoesik Supply Room Key is obtained through random loot โ found in loot containers, on enemies, or as a drop from Lieutenants you eliminate during a deployment. Some Story Missions also reward keys, so it’s worth keeping that in mind as you progress your operator.
The best habit is to open every loot container you come across during your runs. Keys turn up regularly if you’re looting consistently, and this Epic key can appear anywhere on the map.

Is the Hoesik Supply Room Worth Using Your Key On?
Yes โ especially if you’re running a solo or small squad and want a low-risk, decent-reward stop. The area around the Rice Mill doesn’t see a lot of player traffic, the AI is medium threat at worst, and the room itself gives you multiple loot sources in one hit.
For a quick in-and-out run, land at Imjin Farmland, clear the office building, loot the supply room, check the surrounding farmland for any extra containers, and exfil from the nearest extraction point. It’s a clean, efficient run if you play it right.
