Sgt. Ricardo Ramirez, a combat replacement for 1st Battalion, 5th Marine Regiment, wades through an irrigation canal to move into a night observation post in Sangin, Afghanistan, Aug. 5. In February of 2006, Ramirez was wounded in action while serving in Iraq with 3rd Bn., 5th Marines and two years later became the first hand-amputee to re-enlist in the Marines Corps. Since then the multiple-tour combat veteran of both Iraq and Afghanistan has served as an urban warfare instructor, attended the pre-sniper course at division schools and stayed close to his infantry roots.
