I'd be talking contact and evade maneuvers if shit went south to the point I can't talk my way out. I wouldn't charge head on to these fuckers because thats not only stupid, its suicidal. Besides, who will they know to hunt down if nobody survives to report me? Hide or ditch my firearm, condition or get my mind into thinking like a panicked civilian tourist and if approaced, I don't think it's in their best interest to kill an American who appears to have the same views as them.
Equally so proper training > cool gear.
Somehow I made it into the Corps so I have that in my favor whenever I EAS and can do cool shit like this willy nilly
