Marvin Glenn Shields (December 30, 1939 – June 10, 1965) was the first and only United States Navy Seabee to be awarded the Medal of Honor.

[2] Seabee Team 1104 was next assigned to a newly established Army Special Forces Camp at Dong Xoai about 55 miles northwest of Saigon arriving on June 4, to assist in repair and construction of the compound which included an adjacent compound with the district headquarters building.

After four more hours of fighting, and greatly weakened, Shields volunteered to help Special Forces Second Lieutenant Charles Q. Williams who now was the acting commander since the Special Forces commander was one of the first badly wounded in the battle,[3] destroy a Vietcong machine gun outside the perimeter which was threatening to kill everyone now in the adjacent district headquarters building which was now under the Williams's command and its occupants holding off the Vietcong attackers from all sides.

[4] Shields was posthumously presented the Medal of Honor at a ceremony at the White House on September 13, 1966.

His wife received the award from President Lyndon B. Johnson in the presence of his father, mother, daughter, and brother.

All twenty of the Seabees and Special Forces soldiers were personally awarded for their actions at Dong Xoai.
