The Juggernaut's combination of high health, strong weapons, and defensive perks makes them incredibly resilient on the battlefield. They can effectively draw aggro from enemies, allowing teammates (if playing co-op) to focus on objectives or take down priority targets. Example: In a high-hazard mission with a swarm of Glyphids, the Juggernaut can use their shield and heavy weapons to hold the frontline, protecting teammates while they clear out the smaller enemies.
