If a member of a team of soldiers/police, be the strong, quiet leader type...not the loud, obnoxious slogan-spewing type. If the latter, you're probably going to die two seconds after you get your shit together and start doing something heroic. But if the former, your chances of survival are quite good, and will probably be the guy who kills the bad guy and gets laid towards the end of the movie.
If in a movie by Eli Roth...you're all fucked. Anyone alive by the end of the first movie will be killed in the opening minutes of the sequel.
