Pushing a hospital bed through a war zone sounds ridiculous. In Call of Duty: Modern Warfare 4’s DMZ, it’s one of the tensest jobs you’ll take.

What Is Operation Critical Extraction?
DMZ splits its activities into Story Missions and Dynamic Operations. Story missions are named operations with a briefing, a threat assessment and main objectives. They’re designed for cooperative play, and this one drops a squad into a modern hospital with tight interior corridors.

The brief is simple and nerve-wracking. A high-value target, General Kang, is inside Mirae General Hospital. You find him, then move his bed out alive. You’re escorting a person, not grabbing loot, so every firefight now has something to protect.
Why This Mission Is Tricky
Hospitals are close-quarters by nature. Narrow halls, doorways and corners favour whoever hears the other side first. Meanwhile, DMZ lobbies are crowded, and the early-access mode has no PvE-only setting. Other squads may be hunting the same objective, or hunting you for what you carry.
Expect trouble from three sources:
- AI forces guarding the area.
- Rival squads who can hear your fights and move in.
- The clock, since the longer you stay loud, the more attention you attract.
Smart Tips for Your First Run
These are general extraction-shooter tactics rather than confirmed mission steps, so adjust once you see the layout.
- Bring a full squad if you can. Someone has to push the bed while others hold angles and cover doors.
- Assign roles before you load in. One person moves the target, one watches the rear, one clears ahead.
- Move quietly early. Stealth matters in DMZ, so don’t announce yourself in the first hallway.
- Loot smartly. Your backpack starts empty, so grab supplies as you go, but don’t let greed delay the mission.
- Plan your exit. Extraction is by helicopter, and reaching it is where many runs fall apart.
How DMZ Progression Helps
Progress in DMZ is permanent. Every deployment feeds your DMZ level (1 to 70), unlocks Forward Operating Base stations and awards printer recipes. A successful run builds toward stronger loadouts next time, which is why story-mission rewards matter beyond the cash.
Check your DMZ Orders too. They’re reliable mission directives that raise your level and stock your stash. Early orders include clearing a Police Station and cracking a safe for ¤5,000 in cash.
Other Story Missions on the List
Critical Extraction isn’t the only operation. Others include Operation Silent Ledger (Cheongun Village casino and a vault), Operation Shopping Hacks (NuriGO Mall) and Operation Grid Assault. Some missions unlock other options in the mode, so finishing a few early can open more of DMZ.
