Brother In Arms Mission Guide DMZ – How to kill the Sniper and Rhinoceros

Brother In Arms is a Tier 4 mission for the Redacted faction in Call of Duty: Warzone DMZ. The mission challenges you to visit a locked section of the Koschei Complex and kill the two commanders hiding there. Here's a guide in which I've detailed how you can visit the Factory Wing area and carry out the operation.

Brother In Arms DMZ Mission

• Enter the Factory Wing of the bunker.
• Kill the Sniper in the same deployment.
• Kill the Rhinoceros in the same deployment.

How to enter the Factory Wing of the bunker

If you've already visited the Shopkeeper in Koschei Complex for the previous mission, you will not have much trouble finding the Factory Admin. Here's a quick summary of how to visit this area:

• Enter Koschei Complex via any entrance in Al Mazrah and make your way to the Chemical Plant.
• Look for the Factory Admin Key inside the vents in the dark central area.
• Use the key to unlock bunker door A1 or A2, which should be in the west direction. This will take you to the Factory Admin section where the shop is.

Once you're there, keep pushing in fighting off the enemies in your path until you reach the Factory Wing. This first room of this section will have several machinery and partition walls. Upon reaching here, you'll also get the notification for The Rhinoceros and The Sniper.

Move forward and you'll find stairs that will take up one floor up. Follow the path that'll lead you to the area with large yellow chemical containers and a locked door that says Secured from other side. This door leads to the Sniper and will unlock only after you've killed the Rhino, who's on your level.

How to kill the Rhinoceros in Koschei Complex DMZ

The Rhinoceros commander stays in the center of the area by the yellow containers and wooden boxes. I once tried and successfully killed him while playing solo, but it was very difficult and time-consuming. That's because the Rhinoceros has a tremendous HP and you'll need several magazines of bullets to kill him. Hence, go prepared with lots of ammo boxes.

Also, maintain your distance as he'll melee you if you get too close. He'll also call in armored reinforcements, which you'll have to deal with. To make things easier, I suggest you use a decent Shotgun like the KV Broadside to take out the boss. That said, the best way to kill the Rhinoceros is by using a Bomb Drone killstreak, which you can bring into Koschei Complex from Al Mazrah.

How to kill the Sniper in Koschei Complex DMZ

After killing the Rhinoceros, the door to the Sniper will be unlocked behind you. Take the stairs up, carefully defuse the tripwire grenade and you'll see the Sniper with a red laser coming out of his weapon. The boss is very accurate so don't challenge him if you're low on health.

Most importantly, beware of the C4 laser traps, and don't cross them unless you'd like to be blown up. You can crawl under the lasers, find the C4, and defuse the charge to move ahead freely. Just like the Rhino, the Sniper has high HP but you can very easily kill him using a Bomb Drone. Therefore, make sure to bring two Bomb Drone killstreaks with you into the bunker.
