Julio Vargas, 23
Vargas was killed by a roadside bomb while on patrol in Helmand province, Afghanistan, according to military officials. Enlisting in the Marine Corps in February 2008 was just another step in Vargas' life plan. He hoped to complete his duty and then go to college to gain the skills needed to specialize in forensic policing.
