The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pleasure in presenting the Silver Star to Sergeant First Class Jeffrey A. Duncan, United States Army, for gallantry in action against an armed enemy while serving as a Platoon Sergeant for a Task Force from 3d Battalion, 75th Ranger Regiment, from 31 March 2003 to 9 April 2003 during Operation IRAQI FREEDOM. Sergeant First Class Duncan directed accurate and deadly machine gun fire against enemy positions which helped his men move into a dominating position for rapid attack on advancing enemy soldiers. While under intense attack, Sergeant First Class Duncan and his men saved a wounded enemy soldier and took several prisoners. Fearlessly he volunteered to return to the platoon’s position by foot to coordinate return fire on the enemy. Sergeant First Class Duncan’s courage, vision, and professional competence directly contributed to the overall success of the Task Force. Throughout his distinctive accomplishments, Sergeant First Class Duncan reflected great credit upon himself, the Task Force, and the United States Army.
