Smoke

Lore
Smoke is an infamous member of team Rainbow Six after the Grand Jury investigation into his HRSSHT (Humane Really Safe Seriously Humane Toxic-babes) in season two. Smoke's HRSSHT is a well known sleepy juice that puts terrorists to sleep in a very humane fashion and noone seriously believe allegations otherwise, right? I mean, dangerous murder gas stuff is illegal. Smoke would never break the law, he's an officer of it!

The manufacturing of HRSSHT is a secret which only Smoke is privy to. Despite claims that the toxic babes are compressed farts gathered in his hermetically sealed suit, Smoke definitely uses some other undisclosed method.

Smoke joins the Blitz crew on occasion, usually filling the role of comic relief. Despite this, he typically performs quite well in the series, and is considered by many Siege enthusiasts to be in the top tier of operators to appear on the show. It's believed that his seldom appearances are an effort by the writers to keep his strength as an operator from stealing the spotlight from the rest of the cast.
