"For extraordinary heroism as Second Squad Leader, Third Rifle Platoon, Company F, Second Battalion, 1st Marines, in the Thua Thien Province, Republic of Vietnam, on 28 February 1966. While his company was engaged in a search and destroy operation, it was taken under heavy machine gun and mortar fire by en entrenched Viet Cong battalion.
Without hesitation, Corporal Casebolt maneuvered his squad through intense hostile fire in order to position them in a location where they could block the enemy's retreat. His skillful deployment of his squad enabled his men to kill approximately twenty-five Viet Cong and successfully stop the retreat of many others. When an enemy squad attempted to envelop his squad from the left, Corporal Casebolt and two other Marines assaulted the Viet Cong squad, killing them all.
Without stopping to catch his breath, he gave orders to his squad to cover him with fire while he crossed a seventy-meter rice paddy in an attempt to destroy an enemy mortar position that he had detected. With complete disregard for his own safety he aggressively ran across the open rice paddy toward the enemy shouting instructions to his squad and directing their fire.
When he was almost across the open area, the heavy enemy fire knocked him into the rice paddy. Although mortally wounded, he crawled to a mound of earth where he could observe the enemy. From this position, and still the object of intense enemy fire, Corporal Casebolt continued to direct his squad's fire by pinpointing the enemy positions for them and ordering them to deploy to positions where they could better block the Viet Cong retreat.
By his tremendous devotion to duty, professional ability and inspiring leadership, Corporal Casebolt upheld the highest traditions of the Marine Corps and the United States Naval Service.
He gallantly gave his life in the cause of freedom.
