For conspicuous gallantry and intrepidity in action while serving as a Radio Operator with the Second Battalion, Thirteenth Marines. First Marine Division in connection with operations against the enemy in the Republic of Vietnam. On 18 May 1968 Corporal JACKSON was assigned to an artillery forward observer team supporting Company M, Third Battalion, Twenty-Seventh Marines during Operation Allen Brook. Upon being helicopter lifted into an area south of Da Nang, the Marines came under intense hostile fire as they debarked from the aircraft and sustained numerous casualties. Realizing the seriousness of the situation, Corporal JACKSON unhesitatingly organized several Marines to evacuate the injured men. Undaunted by the enemy fire he repeatedly led the Marines about the fire- swept area and supervised the expeditious evacuation of the casualties. Although two of his men were seriously wounded, he continued his resolute efforts ensuring that all of the wounded were moved to covered positions. On 24 May, Company M established contact with a large North Vietnamese Army force. Fearlessly maneuvering across the fire-swept terrain, Corporal JACKSON delivered water and ammunition to the forward positions and evacuated casualties to positions of relative safety. Disregarding his own safety, he removed his protective vest and discarded his weapon in order to carry the maximum amount of supplies. On 26 May, Company M was again heavily engaged with the enemy. Alertly observing a hostile soldier occupying a bunker, Corporal JACKSON immediately delivered a heavy volume of fire and pinned down the North Vietnamese soldier. Assisted by another Marine, he maneuvered forward to the position and captured the enemy, seizing an antitank rocket launcher, an automatic rifle and a large amount of ammunition. By his courage, bold initiative and unwavering devotion to duty in the face of great personal danger, Corporal JACKSON contributed significantly to the accomplishment of his unit's mission and upheld the highest traditions of the Marine Corps and of the United States Naval Service.
