DMZ Brothers in Arms: Rhino & Sniper Guide

The Brothers in Arms mission stands as one of the most challenging Tier 4 tasks in the Redacted faction lineup within Call of Duty: Warzone’s DMZ mode. Players must infiltrate the foreboding Koschei Complex, a underground facility brimming with dangers, to neutralize two formidable commanders known as the Sniper and the Rhinoceros. This guide provides a comprehensive roadmap to success, covering preparation, navigation, combat strategies, and extraction, whether you’re playing solo or with a squad. With the right approach, you can complete this objective in under two minutes and unlock valuable rewards like weapon cases.

Understanding the Mission Requirements

At its core, Brothers in Arms demands precision and preparation. You need to access a restricted Factory Wing section inside the Koschei Complex bunker. Once there, eliminate both bosses in a single deployment without extracting prematurely. Success grants progress toward faction reputation, exclusive blueprints, and access to high-value loot caches. Failure often stems from inadequate gear or poor positioning, so planning is key.

The Koschei Complex itself is a multi-level labyrinth filled with AI guards, environmental hazards, and locked doors. Entry typically occurs via Al Mazrah’s southern tunnels after acquiring a specific key or completing prerequisite exfils. Time your run during low-player lobbies to minimize PvP interference.

Essential Preparation Before Deployment

Success hinges on loadout choices made in Al Mazrah. Prioritize mobility and utility over raw firepower initially.

• Bomb Drones: Purchase two from buy stations at 12,000 USD each. These are the meta choice for instant boss kills.
• Loadout Items: Precision Hostage pistol for close encounters, semtex grenades, and dead silence for stealth.
• Armor and Plates: Three-plate setup with high-tier vests to withstand AI barrages.
• Contracts: Secure a Nearby Buy Station contract en route to fund drone purchases.

Fly a chopper between buy stations if needed to scout drone availability. Stock up on ammo and stims as backups. Squads should assign roles: one drone operator, flankers, and a reviver.

Navigating to the Factory Wing

From the Koschei entrance, proceed through dim corridors lined with chemical vats and patrolling guards. Key landmarks include a descending staircase flanked by yellow barrels and a secured door labeled ‘Locked from Other Side.’

1. Clear initial patrols silently using suppressed weapons.
2. Descend stairs to the chemical storage area.
3. Avoid laser-triggered explosives by crawling underneath or shooting the C4 packs.
4. Position at the threshold without entering the boss arena to maintain element of surprise.

Strategy for Defeating the Rhinoceros

The Rhinoceros lurks amid wooden crates and massive yellow containers, wielding a riot shield and heavy weaponry. His immense health pool demands sustained damage or one-shot potential.

Primary Method: Bomb Drone One-Shot

Approach the doorway but halt before the interaction prompt. Deploy the drone, guiding it directly overhead the boss while he’s stationary. Detonate immediately for a guaranteed kill. This prevents him from shielding or calling reinforcements. Expect no further spawns in the area post-elimination.

Solo Backup Tactics:

• Equip KV Broadside shotgun with slugs for shield penetration.
• Flank from elevated catwalks, prioritizing headshots.
• Lob semtex over cover to strip armor, then burst fire.

Team Coordination: One player drones while others suppress incoming bots. Time the kill before heavy reinforcements arrive.

Pro Tip: Kill the Sniper first in some layouts to avoid overlapping spawns, adjusting drone angles to bypass shields.

Tactics for Eliminating the Sniper

Post-Rhino, a door unlocks behind you. Ascend stairs, defuse tripwires, and enter the elevated perch where the Sniper mans a long-range rifle with pinpoint accuracy.

Bomb Drone Execution:

Repeat the doorway drone tactic: hover above before he spots you, detonate for instant death. His red laser sight gives away position—use it to your advantage.

Alternative Approaches:

• Stealth Crawl: Belly under lasers, plant charges at his feet.
• High-Ground Push: Scale side ladders, drop flashbangs, and shotgun rush.
• Distraction Play: Squad member draws fire while drone flies in.

The Sniper lacks a shield but compensates with precision; peek sparingly and heal proactively.

Post-Kill Rewards and Extraction

Both bosses drop Secure Room Keys upon death, unlocking adjacent vaults with rare loot: cash stacks, killstreaks, and mythic weapons. No more AI spawns means safe looting.

Extract via the nearby exfil point or secure the Weapon Case for bonus rewards. Mission completes automatically upon double-kill confirmation.

Solo vs. Squad: Comparative Strategies

Solos thrive with patience; squads leverage speed.

Common Pitfalls and How to Avoid Them

• Drone Shootdown: Launch from cover, detonate fast.
• Shield Absorption: Frontal overhead attack only.
• Spawn Waves: Prioritize Sniper first if overlapping.
• Laser Traps: Always defuse before advancing.

Advanced Tips for Speedruns

For leaderboard glory, chopper to multiple stations pre-drop. Use precision airstrikes as backups. Practice drone paths in custom games. Track patch notes for balance changes.
