In 1968 the US Army assigned a young sniper to the 5th Special Forces compound in Nha Tong, Vietnam. His mission: Disrupt the enemy's command structure, scout Vietcong positions, and ambush the enemy in the dead of night. For him, success depended on a rifle, a target, and a clear line of sight. In Line of Sight: Vietnam, your job is to locate elusive enemy soldiers and pick them off one by one. Whether patiently waiting for the enemy to show himself or delivering a preemptive strike, the method is the same--be quick, be quiet, and be careful.
