The whole FOB was covered in dust and smoke, looking like something out of an old Western movie.

“I’ve never seen the enemy do anything like that,” said Walker, who was medically evacuated off the FOB in one of the first helicopters to arrive. “It’s usually three RPGs, some sporadic fire and then they’re gone … I don’t where they got all those RPGs. That was crazy.”

Two hours after the first shots were fired, Stafford made his way — with help — to the medevac helicopter that arrived.

“It was some of the bravest stuff I’ve ever seen in my life, and I will never see it again because those guys,” Stafford said, then paused. “Normal humans wouldn’t do that. You’re not supposed to do that — getting up and firing back when everything around you is popping and whizzing and trees, branches coming down and sandbags exploding and RPGs coming in over your head … It was a fistfight then, and those guys held ’ em off.”

Stafford offered a guess as to why his fellow soldiers fought so hard.

“Just hardcoreness I guess,” he said. “Just guys kicking ass, basically. Just making sure that we look scary enough that you don’t want to come in and try to get us.”
