|Fourth||Weakness is Melee|
They wear orange hazmat suits. They are quite capable of easily killing an off guard player due to the way they attack. They are very durable towards gunshots. It is recommended to use melee unless you are low in health or very vulnerable to attacks.

|Rare?||Somewhat. More common in Operations|
