This Is Why You Shouldn’t Mess With People Who Work in Retail

In her civilian life, [Sgt. Leigh Ann Hester] was the manager of a retail store, and if you’ve ever worked at a place like that, you KNOW that’s a fucking tough job and you have to be a total hardass to do it. Well Sgt. Hester got to take out some of her pent-up aggression at dipshit customers on these hapless douchebag insurgents, as she went up and down the trenches capping assholes with her assault rifle and clearing the ditch system of enemy combatants. When she ran out of ammunition, she sprinted back to her Humvee, grabbed some extra mags, and ran right back into the battle. She even moked out an RPG-toting Iraqi out with her underbarrel-mounted M203 automatic grenade launcher.

From here.
