Use the Hoesik Supply Room Key at the Rice Mill in southeastern Imjin Farmland on the Hajin map, grid D8. The lock is not in the main mill production building: enter the southern office or two-story building, go upstairs from the ground-level entrance, and interact with the locked door. Guides label the destination as either the first or second floor, but the building and upstairs route are consistent.
Where is the Hoesik Supply Room in MW4 DMZ?
The room is inside the Rice Mill, a Stronghold in southeastern Imjin Farmland at grid D8 on Hajin. Use the southernmost office/two-story building as your landmark. Searching the large production building can waste time because the Hoesik door is in the separate southern structure.

How do I reach the Hoesik Supply Room door?
- Travel to the Rice Mill in southeastern Imjin Farmland, grid D8.
- Identify the southernmost office or two-story building, rather than the main mill production structure.
- Enter at ground level and locate the interior stairs.
- Climb upstairs and interact with the locked Hoesik Supply Room door while the key is in your inventory.
Some walkthroughs call this the first floor and others call it the second floor, reflecting different floor-label conventions. Follow the building and stair landmarks instead of relying on the number shown in a guide.
How do I get the Hoesik Supply Room Key?
The Hoesik Supply Room Key is an Epic item acquired through random loot. No source establishes a guaranteed mission, boss, container, or vendor that always awards it, so repeated runs cannot promise a particular drop.

When you find the key, place it in a Secure Slot when possible. Activision’s DMZ guidance explains that items kept outside a Secure Slot can be lost if an exfiltration fails. Securing the key before deploying gives you a better chance of bringing it into a run where the Rice Mill is safe to approach.
What loot can the Hoesik Supply Room contain?
The room’s contents roll separately each match, so opening it does not guarantee a named weapon or a fixed payout. Reported containers include a weapons locker, a safe, and a cache. Guides also report Epic materials, cash, and possible weapon or document drops.

| Reported contents | How to interpret it |
|---|---|
| Weapons locker | Container type reported in the room; weapon contents vary |
| Safe | May provide cash or other rolled loot |
| Cache | Additional randomized items |
| Epic materials | Possible high-rarity crafting or sellable materials |
| Weapons or documents | Possible drops, not guaranteed |
One documented match example listed a Signal 50, Infantry Invasion Plans, and Oris 8.6. Those are examples rather than a fixed reward table. No reliable published percentage for key drops, room loot odds, or average room value has been established.
Is the Rice Mill safe to enter?
No. The Rice Mill is described as a Stronghold with AI soldiers, aerial drones, and possible nearby roaming-boss activity. Clear angles before climbing the stairs, watch the approach for drone pressure, and avoid opening the door while your squad is exposed to the courtyard or nearby patrols.

DMZ is an extraction environment: operators loot, complete objectives, fight AI and rival players, and must extract to keep rewards. The available location information does not quantify player-versus-player danger around D8, so treat the route as variable rather than assuming a quiet run.
Is the Hoesik Supply Room worth a detour?
It is most worthwhile when you already have the key and are operating near southeastern Imjin Farmland. The room can combine several valuable container types and Epic materials, but randomized loot means the result may not justify a long cross-map trip.

- Make the detour when: you have a secured key, adequate armor and ammunition, and another objective near the Rice Mill.
- Delay it when: your squad is under-equipped, the Stronghold is heavily contested, or extraction time is short.
- Leave after opening: search the reported containers, collect only what fits your plan, and prioritize a safe exfil over chasing an uncertain extra roll.
What should I remember before deploying?
- Set a waypoint for the Rice Mill in southeastern Imjin Farmland, grid D8.
- Look for the southern office/two-story building, not the main production hall.
- Keep the Epic key in a Secure Slot whenever possible.
- Expect AI, drones, and possible boss activity at the Stronghold.
- Plan for randomized contents; no weapon, document, cash amount, or material stack is guaranteed.

What happens to the key if I fail to exfil?
Unsecured inventory items can be lost when an exfil fails. Keeping the key in a Secure Slot helps preserve it for a later deployment.
Should I clear the Stronghold before climbing to the room?
Clearing nearby AI and checking for drones is safer than rushing the stairs. The Rice Mill can also have roaming-boss activity, so listen and scan before opening the upstairs door.
