These guys are not really meant for combat and are only seen in the first mission. They wear a pink hazardous environment suit and carry the Feline. They are really weak and most weapons will kill them in a few shots. They do not carry grenades.
In-game Character Information Edit
There are many areas within the dome and its perimeter that are extremely hazardous to health. Considered a form of punishment among the involves who make up the bulk of those sent on "hazmat" duty, CBRN units are provided with a protective suit, which offers only limited survivability in such conditions.
