There's free fire zones and cold fire zones.  A free fire zone means you're locked and loaded, safety off,  and eyes in the back of your head. Cold fire zone is a term I made up. It's one of those places American soldiers get sent to keep the peace, or enforce the peace, or make the peace. Some places the weather's cold. Most places the people are cold. Ain't no heroes in keeping people from killing each other. Just another day in doin' the job Uncle Sugar sent us to do.
