The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pride in presenting the Distinguished Service Cross (Posthumously) to Specialist Fourth Class Onsby Ray Rose (ASN: RA-15697809), United States Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company D, 1st Battalion, 5th Cavalry, 1st Cavalry Division (Airmobile). Specialist Four Rose distinguished himself by exceptionally valorous actions on 18 May 1966 while serving as radio-telephone operator for a company involved in providing security for a helicopter landing zone deep in hostile territory. Early in the evening, his company was attacked by a large enemy force using automatic weapons, small arms and hand grenades. As the fierce fighting increased, a machine gunner was wounded, weakening defenses in a critical position. Specialist Rose, without regard for his own safety, grabbed a machine gun and braved the withering fire to take his place on the line. His heavy and accurate fire on the enemy caused many casualties and forced the insurgents to retreat. As the firing subsided, an enemy hand grenade landed in his position. Seeing that he could not throw it away before exploding, Specialist Rose bravely threw himself on the grenade to save his assistant gunner. His immeasurably courageous action to save his comrade resulted in the loss of his life. Specialist Four Rose’s extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
