Noah Lindt heard the call of duty after the tragic events of 9/11. Despite a hampering medical condition that kept him on the outskirts of his high school class, he was accepted into the Marines where he found out he had a singular skill. He could outshoot almost anyone. Marksmanship alone is not enough to be a successful scout sniper. Teamwork and mental discipline are paramount, and the self-professed loner has problems adjusting to his spotter as well as the rest of his platoon when they deploy to Ramadi, "the most dangerous city on earth." As a HOG, a "Hunter of Gunmen," Corporal Lindt has to break through his personal barriers and become not only a marksman, but an NCO of Marines if his team will make it through numerous engagements with an enemy who has put a bounty on all American snipers.
