The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Distinguished Flying Cross to Warrant Officer One (WO-1) Roscoe C. Armstrong, United States Army, for heroism while participating in aerial flight evidenced by voluntary actions above and beyond the call of duty in the Republic of Vietnam. Warrant Officer Armstrong distinguished himself by exceptionally valorous actions while piloting helicopter gunships in support of an Allied ground unit in heavy enemy contact. Despite the heavy enemy fire, he placed accurate and intense suppressive fire on the targets, kept abreast of the situation and kept a constant volley of fire on the enemy as they tried to retreat. His three attacks resulted in three secondary explosions and an estimated 25 enemy casualties. His exceptional courage and complete devotion to duty were demonstrated throughout the day as he repeatedly exposed himself to heavy enemy fire. The aerial professionalism and complete composure Warrant Officer Armstrong demonstrated were vital to the complete success of this mission. His actions were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
