Broken Resupply is a multi-step Dynamic Operation on the Hajin map in Call of Duty: Modern Warfare 4 DMZ. It begins with hacking a Comms Server at NuriGO Mall before sending you to a marked vehicle, a security safe, and a locked room containing a WMD.
The trickiest parts are finding the Bomb inside the camper's trunk, locating the safe that reveals the keypad code, and knowing which objectives actually belong to Broken Resupply. Other DMZ Orders can remain active at the same time, making the mission tracker confusing.
This walkthrough explains the complete objective sequence, where to find the required items, how to use keypad code 1957, and what happens after you finish the operation.

Quick Answer: How to Complete Broken Resupply
To complete Broken Resupply in MW4 DMZ, follow these six steps:
- Hack the Comms Server at NuriGO Mall.
- Defend the Location until the server defense is complete.
- Loot the Marked Item from the Trunk to collect the Bomb mission item.
- Find the Keypad Code in the Safe inside the marked building in NuriGO West.
- Use code 1957 to unlock the secure keypad door.
- Plant the Bomb on the WMD to complete Broken Resupply.
Broken Resupply keypad code: 1957
The operation completes when the WMD objective is finished. You can then continue other DMZ activities or head toward extraction.
All Broken Resupply Objectives
Broken Resupply takes you through several locations in the NuriGO area of the Hajin map. Each completed objective reveals the next step, so follow the active mission marker rather than searching for every location in advance.
| Step | Objective | Required Action |
|---|---|---|
| 1 | Hack the Comms Server | Interact with the marked server |
| 2 | Defend the Location | Complete the server defense |
| 3 | Loot the Marked Item from the Trunk | Collect the Bomb mission item |
| 4 | Find the Keypad Code in the Safe | Search the marked security safe |
| 5 | Use Code 1957 to Unlock Keypad | Enter 1957 at the secure door |
| 6 | Plant the Bomb on the WMD | Complete the final bomb objective |
Important: Lieutenant hunts, clinic supply tasks, and SAM Site activities can appear alongside Broken Resupply. These are separate DMZ activities and are not part of the six-step operation sequence.
1. Find and Hack the Comms Server
The first objective is Hack the Comms Server.
Head toward the marked location at NuriGO Mall and enter the building containing the server. The terminal is inside an office-style interior, so follow the objective marker through the building rather than searching the surrounding streets.
Approach the server until the interaction prompt appears:
Hack the Comms Server
Activate the terminal to begin the hack.
The interaction starts a timed sequence. Once the hack step is complete, the operation transitions into a defense objective.
Prepare Before Activating the Server
Before interacting with the terminal, check your ammunition and armor.
The next phase involves fighting enemies around the server location, so it helps to reload your weapons and insert armor plates before the encounter begins.
You don't need to eliminate every hostile across NuriGO Mall. Concentrate on enemies threatening the objective area and the routes leading into the building.
2. Defend the Server Location
After the hack, the next objective is Defend the Location.
A defense marker appears while a timer counts down. Your task is to survive the encounter and finish the defense phase before moving to the next mission location.
The fighting takes place around the reception area and nearby interior corridors. Enemies can approach from multiple directions, making it important to watch your surroundings.
Best Way to Handle the Server Defense
Use the reception counter and nearby cover to avoid remaining exposed in open areas.
Watch for hostile indicators as enemies move closer. Reload during safe openings and replenish your armor when necessary.
Avoid chasing enemies too far into other rooms. The priority is completing the objective, not increasing your kill count.
Stay focused on the defense marker and the remaining timer.
How to Know the Defense Is Complete
The game confirms the objective with:
Step Complete — Defend the Location
Once this notification appears, the operation updates to Loot the Marked Item from the Trunk.
If the defense step remains active, the server portion of Broken Resupply is not finished yet, even if the initial hack was successful.
3. Find the Camper and Loot the Bomb
The third objective is Loot the Marked Item from the Trunk.
Leave the server location and follow the new waypoint toward the marked vehicle in the NuriGO area.
The target is a white camper-style vehicle. It can be encountered around NuriGO East, while the trunk is accessed in NuriGO West during the route.
Follow the active objective marker to locate the vehicle rather than relying on a fixed street position.
How to Get the Bomb from the Camper Trunk
- Reach the marked camper.
- Move to the rear of the vehicle.
- Interact with the trunk storage compartment.
- Find the Bomb, listed as a mission item.
- Take the Bomb to finish the trunk-looting objective.
The game then confirms:
Step Complete — Loot the Marked Item from the Trunk
The next objective directs you to find the keypad code in a safe.
Why You Might See Enter Camper Instead
When approaching the vehicle, you may see an Enter Camper interaction prompt.
That prompt lets you enter the vehicle, but it is not the trunk-looting action.
If you're trying to retrieve the Bomb, move to the rear storage compartment and open its inventory.
You do not need to drive the camper to complete the trunk objective. The required action is collecting the Bomb mission item.
4. Find the Keypad Code in the Safe
After collecting the Bomb, the objective changes to:
Find the Keypad Code in the Safe
Follow the waypoint toward the marked building in NuriGO West.
Inside, search for a back office or storage area containing a green security safe.
Where to Find the Safe
The safe is positioned on the floor near green storage crates and a bulletin board.
Enter the building, follow the objective marker into the interior rooms, and look for the heavy green safe in the back office.
Approach it and interact with the container to search its contents.
The safe contains several items, including valuables and a Hard Drive identified as a mission item.
Check the contents and complete the active objective before leaving. Once the game confirms that you've found the keypad code, you can proceed to the next step.
The completion notification reads:
Step Complete — Find the Keypad Code in the Safe
What if Your Backpack Is Full?
You may encounter a Backpack Full warning while inspecting the safe.
Some items inside are valuables that can be extracted and sold for cash. Don't confuse these optional valuables with the active mission objective.
Check whether the keypad-code objective has been marked complete before leaving the room. If it has, follow the updated waypoint toward the locked door.
5. Enter Keypad Code 1957
The keypad code for Broken Resupply is:
1957
After completing the safe objective, the game displays the instruction:
Use Code 1957 to Unlock Keypad
This is the combination needed for the secure door.
How to Unlock the Keypad Door
- Follow the objective marker toward the locked room.
- Find the wall-mounted digital keypad beside the secure door.
- Approach it until Enter Access Code appears.
- Interact with the keypad.
- Enter 1957 and confirm the code.
After the correct entry, the game confirms:
Step Complete — Use Code 1957 to Unlock Keypad
The secure door unlocks, allowing you to enter the final objective area.
What if Code 1957 Doesn't Work?
First, check whether Find the Keypad Code in the Safe is marked complete.
If that objective is still active, return to the marked safe and finish the required interaction.
Also make sure you're using the keypad associated with Broken Resupply rather than another locked door.
Once the safe step is complete, follow the active objective marker to the correct keypad and enter 1957.
6. Plant the Bomb on the WMD
After unlocking the secure door, the final objective appears:
Plant the Bomb on the WMD
Enter the unlocked area and follow the objective marker toward the WMD.
Approach the marked target and complete the bomb-placement interaction.
The Bomb collected from the camper trunk is the mission item associated with this final objective.
Once the bomb objective is finished, the game displays:
Operation Complete — Broken Resupply
This confirms that you've completed the Dynamic Operation.
You do not need to finish the separate Lieutenant hunt or SAM Site activity to receive the Broken Resupply completion notification.
What to Do if You're Stuck in Broken Resupply
If Broken Resupply appears to stop progressing, check the active objective before searching for another location.
The Comms Server Hack Is Complete, but Nothing Happens
Look for the Defend the Location objective.
The initial hack and the subsequent defense are separate steps. Finish the defense phase before leaving the server area.
You Found the Camper but Can't Find the Bomb
Move to the rear of the camper and open the trunk inventory.
The Bomb is a mission item inside the storage compartment. Entering the vehicle does not collect it.
You Found the Safe but the Objective Is Still Active
Interact with the marked safe and check its contents.
Make sure the game confirms Step Complete — Find the Keypad Code in the Safe before moving toward the keypad.
The Keypad Door Won't Unlock
Confirm that the safe objective is complete, then use the marked keypad and enter 1957.
If you're at an unrelated locked door, return to the active Broken Resupply waypoint.
The Operation Is Complete, but You're Still in DMZ
This is normal.
Completing Broken Resupply does not automatically end the deployment. You can still have active side activities and must extract separately if you want to finish the deployment successfully.
What Happens After Completing Broken Resupply?
The operation finishes when you complete Plant the Bomb on the WMD and receive the Broken Resupply completion banner.
However, the DMZ deployment continues afterward.
You may still have other objectives available, including Lieutenant-related activities and a SAM Site.
Whether to continue those activities or head toward extraction depends on your remaining time and equipment.
Should You Extract Immediately?
If the radiation countdown is running low, extraction should become your priority.
Check the available extraction marker and plan a route that gives you enough time to reach the helicopter.
In the NuriGO deployment, extraction can involve reaching a helicopter landing zone, boarding the aircraft, and waiting for it to depart.
The game confirms a successful departure with Extraction Successful.
Remember that completing Broken Resupply and successfully extracting are two different milestones.
What Rewards Do You Get?
Completing Broken Resupply awards operation progress and XP.
Your final extraction summary may also include banked cash, collected valuables, crafting resources, and other deployment results.
These totals depend on what you accomplished and collected during the deployment. Do not treat the entire extraction payout as a fixed Broken Resupply reward.
Prepare for Your Next DMZ Deployment
If you're planning another DMZ run, review your weapon setup before redeploying.

Final Tips for Completing Broken Resupply
Broken Resupply is easier to follow when you focus on its six main objectives instead of the other DMZ Orders visible on your HUD.
Start by hacking and defending the Comms Server. Then collect the Bomb from the camper trunk, search the safe for the keypad code, unlock the door using 1957, and plant the bomb on the WMD.
Keep an eye on the radiation timer, replenish your armor during combat, and avoid spending too long collecting optional loot when the next objective is already available.
Once the Operation Complete — Broken Resupply banner appears, decide whether you have enough time to continue other activities or whether it's safer to head directly for extraction.
