i'm game. I think Vance fits the modern weapon and normal human style you're looking for here's his sheet-
Name: Vance (AKA "The Laughing Devil")
Class: Mentally unstable, armed and extremely dangerous
Tall with a moderate to somewhat "bulky" build, messy pitch black hair, and one red and one dark blue eye which are barely visible through the lenses of his gas mask. Riddled with scars from growing up in a constant war zone.
Seriously deranged, suffers from PTSD as well as a number of other mental defects that are yet to be properly diagnosed in a clinical setting. Enjoys killing and watching others suffer.
Ballistic/Tactical Vest and armor of the same type covering most of his legs.
A modified GP-5 Gas mask with a refined respiration system and extremely fine filters
Two Taurus Raging Bull Model 500's (both holstered on his lower back)
Two RGO Hand Grenades
Two Tear Gas grenades
A Type 87 Grenade Launcher with a 12 round drum magazine (slung across back if not already being held)
A small ammunition pouch attached to his belt holding .50 caliber rounds for his Raging Bull revolvers.
Two 12 round drum magazines for his type 87 grenade launcher attached to his belt on his back.
A pair of scissors each blade being about 4.5'' long and the handle 3'' long. sheathed on the outer thigh of his right leg.
Vance was born into a war torn country, a civil war that had been going on long before he was even born would determine his fate. When Vance was still a very young boy a squad of rebel soldiers "commandeered" his home, after ransacking the home of any valuables and food they proceeded to kill his family one by one as he watched. When they tried to kill him something in him snapped and he murdered one of the soldiers by driving a pair of scissors into his neck (a pair of scissors he still carries to this day, as a sort of a "security blanket"). Instead of killing him though the commanding officer of the squad ordered that he'd be taken alive and reformed to fight for their cause, seeing promise in the young boy, he stated that he had "The eyes of a killer", and a "Strong survival instinct".
The years passed as Vance was raised on the battlefield his senses sharpened as he honed all the skills necessary for survival in a war zone, he was drugged and brainwashed into believing that the troops of the totalitarian government killed his family and so he would take it out on any enemy troops he would come across. He became something of a legend amongst the rebel soldiers and the government troops came to know him as well, as "the laughing devil" due to his loud fear inducing laughter echoing just before or after an intense battle.
For some reason or another, amidst a heated firefight Vance lost all control. Perhaps it was all the stress the years of fighting had put on his already extremely damaged psyche but nobody will ever know. Vance ended up killing any living thing he could get his hands or sights on; Rebels, government troops, or even civilians. It didn't matter to him anymore, to this day everybody is an enemy to him.
