The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Silver Star to Specialist Fifth Class Steven W. Oller (ASN: RA-18906188), United States Army, for gallantry in action while engaged in military operations against an armed hostile force in the Republic of Vietnam. Specialist Fifth Class Oller distinguished himself while serving as a Senior Medical Specialist with Company D, 4th Medical Battalion, 4th Infantry Division. On 11 May 1969, Landing Zone Oasis came under heavy rocket, mortar, and ground attack by a large North Vietnamese sapper unit. Specialist Oller, with complete disregard for his personal safety, exposed himself to the intense hostile fire to treat the wounded. Moving from bunker to bunker he treated the casualties and carried several of them across a large open area to safety. His actions were directly responsible for the saving of many lives. Specialist Fifth Class Oller’s personal bravery, determination and exemplary devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
