Nothing against SEALs and Green Berets and other Special Operations units. They're elite. But there are a lot of just average, normal guys out there … - David Bellavia

The gunman on the roof was a teenaged boy, maybe sixteen years old. I could see him scanning for targets, his back to me. He held an AK-47 without a stock. Was he just a stupid kid trying to protect his family? Was he one of Muqtada al-Sadr's Shiite fanatics? I kept my eyes on him and prayed he'd put the AK down and just get back inside his own house. I didn't want to shoot him. He turned and saw me, and I could see the terror on his sweat-streaked face. I put him in my sights just as he adjusted the AK against his shoulder. I had beaten him on the draw. My own rifle was snug on my shoulder, the sight resting on him. The kid stood no chance. My weapon just needed a flick of the safety and a butterfly's kiss of pressure on the trigger.
Please don't do this. You don't need to die.
The AK went to full ready-up. Was he aiming at me? I couldn't be sure, but the barrel was trained at my level. Do I shoot? Do I risk not shooting? Was he silently trying to save me from some unseen threat? I didn't know. I had to make a decision.
Please forgive me for this.
I pulled my trigger. The kid's chin fell to his chest, and a guttural moan escaped his lips. I fired again, missed, then pulled the trigger one more time. The bullet tore his jaw and ear off. Sergeant Hall came up alongside me, saw the AK and the boy, and finished him with four shots to his chest. He slumped against the low rooftop wall. "Thanks, dude. I lost my zero," I said to Hall, explaining that my rifle sights were off-line, though that was the last thing going through my mind.

The area around us suddenly erupts with grenades and machine-gun fire. Those shells landed near some Marines, who have finally reached our area. It is about time they get on-line with us. Then again, it is a mixed blessing to have them around. They don't take kindly to the 25mm incoming. Their response sends us diving for cover behind our tracks as .50-caliber machine-gun fire stitches across our street. Rodriguez gets on the radio. The Marines are not apologetic. We are told that they will return any and all incoming fire, friendly or otherwise.

In 2004 in Fallujah, we were involved in so many direct fire engagements. We made eye contact with the enemy. And we lost guys. That was a totally different experience, losing someone that way. You automatically had to address Okay, not only did that just happen, but someone made this happen. That person is still here. House fighting, especially in an urban environment, the sense you most rely on- hearing- is gone. You devolve into an almost animalistic being. Like, I'm smelling this guy. I see a pristine drinking cup on the counter and everything else is covered in dust and grime. A piece of cheese sits on a plate. There's a person here. You become a wolf- just sniffing the air and smelling. Everything stops. Your whole body freezes. You don't breathe. You don't think. All you do is become a single, focused thought: There's a threat here and it needs to be put down.
