TOXO-VIPER
Hostile Environment Trooper
The original Cobra Toxo-Vipers were disparagingly referred to within the ranks as the "Leaky Suit Brigade", and assignment to them was considered severe punishment. The new Toxo-Vipers sport top quality, state-of-the-art equipment, greatly increasing their survival ratio, but they still have to deal with intensely toxic sludge and horrible noxious gases as part of their normal tour of duty.
"Toxo-Vipers have the bad attitudes of permanent latrine orderlies. They don't want to be there, they don't like what they're doing, and they know they're stuck because nobody else will do it. Toxo-Vipers have a grudge against the whole world, and the only thing that makes them feel better is to make the world a nastier place for you to live in."
