What is the Tourniquet in DMZ?

An ability every Operator deploys with. When you are downed, it lets you get back up at 100 health by giving up 50 max health. You are then wounded until you use a Medkit.

Does a Bandage fix a wound in DMZ?

No. A Bandage only restores your max health to 150 for a while. Only a Medkit repairs the wound and makes the Tourniquet available again.

How do I survive radiation in DMZ?

Wear Radiation Gear and a Gas Mask. Together they let you enter the Haneul Nuclear Reactor. Radiation Blockers are a Rare consumable.

MW4 DMZ health guide: Tourniquet, wounds, Medkit vs Bandage

Pre-launch guide. Written from official info released before early access. We update it as the game goes live.

DMZ doesn’t just kill you when your health hits zero. You get second chances, but each one costs something. Knowing which heal fixes what is the difference between exfiling and going MIA.

The basics

You have 150 health.
When you go down, you can use the Tourniquet. Every Operator deploys with it.
The Tourniquet gives up 50 max health to get you back up at 100. You are now wounded.
While wounded, you can’t Tourniquet again until the wound is repaired.

Details: Tourniquet recovery.

Which heal does what

Item	Repairs the wound?	Resets the Tourniquet?	What it does
Medkit	Yes	Yes	Full repair back to 150. The only real fix.
Bandage	No	No	Back to 150 max health for a while
Stim	No	No	Back to 150 for a while; also refills and extends stamina
Pain Killers	No	No	Max health, less damage effects and faster regen for a minute
Self-Revive Kit	–	–	Its own slot: revive yourself. Can be looted or printed.

Important: while temporary health from a Bandage, Stim or Pain Killers is active, you can’t Tourniquet if you go down again. Carry at least one Medkit on any serious run.

Stamina

Tactical Sprint is on by default in DMZ. Sprinting burns stamina until you drop to a normal sprint. These refill and extend it:

Energy Drink: infinite stamina for a while (Common, printable for 10 Chemicals and 10 Metals)
Stim
Smelling Salts: in official footage, infinite stamina plus faster reloads and movement for a short time

See DMZ damage and movement tuning.

Hiding from detection

The Sedative Inhaler makes you immune to all radar, marking systems and thermal for 60 seconds. That’s useful when you’re Wanted. See the bounty guide.

Radiation

The Haneul Nuclear Reactor sits under radioactive vapor. You need:

Radiation Gear and a Gas Mask to get in. Find them at Fire Stations.
Radiation Blockers, a Rare consumable that’s also printable.

Armor is health too

Plates soak damage before your health does. Refill them at Ammo & Armor Caches. See the armor and backpacks guide.

Traits that keep you alive

Trait	Tree	Effect
Free Revive	Survivalist	Your first Wound is repaired automatically
Metabolism	Survivalist, Warfighter	Slowly regain health lost to the Tourniquet
Possum	Warfighter	Once per match, self-revive into Last Stand from death at full health
Numb the Pain	Survivalist	Revives also give Pain Killers and Smelling Salts effects
Consumable Duration	Survivalist	Consumables last longer
Quick Fix	Warfighter	Health regen starts sooner after a kill

Plan them in the skill tree planner.

Where to find healing

Clinics are full of medical supplies, and bathroom cabinets often hold Bandages. You can also print them: the Bandage and Medkit recipes unlock at DMZ Level 2. Costs are in the crafting guide.
