Don't mess up your life/career yet by getting involved in a gunfight-try to stay away from the bad areas and "survive" long enough to get out of there and into the Army, where hopefully you can get a better life and circumstances. You need something very bad and non-lethal. A large bottle of 15% or stronger OC/Pepper spray will clear the whole dang street. It hoses like a fire nozzle sprayer and works.
