The Fire Insurance, Quiet, and Mechanic missions in Call of Duty: Modern Warfare 4 DMZ involve the use of Thermite to destroy enemy vehicles, collecting loot from containers without taking any damage, and performing repairs on a radar truck. Each mission has specific objectives, requiring careful movement, stealth, and the right vehicle parts to complete successfully.
Fire Insurance Mission Guide
The Fire Insurance mission requires you to print five Thermite lethals and stick five enemy vehicles with Thermite.
Print 5 Thermite Lethals
Head to a 3D printer and select the Lethals category. Find Thermite and print five units. Printing extra Thermite can help if you miss any of your targets.
Stick 5 Enemy Vehicles With Thermite
Seek out opposing cars with drivers present approaching your location and bombard them with Thermite. Hitting the same vehicle, which has a driver more than once is perfectly acceptable and can be counted toward the objective. Use this method to complete the five required hits.
Quiet Mission Guide
In order to complete the Quiet mission, you need to loot ten containers located in The Grid without taking any damage. The Grid is situated in the center of the map where the presence of enemy AI makes stealth vital in successfully looting the containers.
Loot 10 Containers in The Grid Without Being Damaged
Head to The Grid and go into one of its larger buildings. Explore the upper levels of the building and check the containers you can loot.
To minimize the chances of being discovered by enemies, attack with quiet firearms. Try to avoid engaging enemies if possible. As the area has a UAV tower, activating it will help you discover enemy locations as well.
If there is a key that you have that can be used to unlock specific rooms with boxes with limited enemies, use it. For solo players, it would be a good idea to have some medical kits in case you get killed, and decoys might also come in handy. Loot 10 containers without taking damage to complete the mission.
Mechanic Mission Guide
The Mechanic mission requires you to repair a radar truck and kill 19 enemies pinged by it. You’ll need to collect vehicle parts before locating and repairing a suitable truck.
Find Radar Truck Parts
Look for gas stations where you can buy parts to repair a radar truck. Parts include car batteries, spark plugs, alternators, and vehicle water pumps, although it may require visiting multiple gas stations to find all parts required for a radar truck repair because different gas stations have different parts.
Since damaged vehicles appear around gas stations, radar trucks may also be seen near other structures. You can check the map for radar truck locations and listen for a voice prompt when approaching one.
Repair a Radar Truck
You must locate a radar truck and check what parts are missing. By interacting with the truck, you can install the parts you have obtained. Some trucks may already have some components installed, which can affect the number of parts you require. If you fail to find a required component, you can extract the parts you have collected and find the missing ones on another run.
Kill 19 Enemies Pinged by a Radar Truck
Once the truck is repaired and the radar truck has become operational, move it to ping nearby enemies. After they are pinged by the radar truck, kill the enemies. Continue searching for enemy targets and buildings until you complete your objective of making 19 kills. Ensure that the radar truck is fixed and working before attempting the elimination objective to complete the PG 15 missions in DMZ.
