Jerry Michael Tate Shriver (24 September 1941 – 10 June 1974), also known by his nickname "Mad Dog", was a Master Sergeant in the United States Army who served in Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) in the Vietnam War.

[3][4][5][6][7][8][9][excessive citations] He took part in operations along the Ho Chi Minh trail, Cambodia and Laos from 1966 to 1969.

Shriver frequently served with Montagnard soldiers, developing a close friendship and respect for their people and donating money and supplies.

He devoted a lot of his time not only to taking part in any mission he could but also to supporting his fellow soldiers financially and with supplies.

On one occasion he asked his superiors for a break but snuck out to the Plei Djereng Special Forces team to fight for several weeks, Shriver took part in a battle that happened on 10 August 1967, Shriver and his team were infiltrating enemy bases and called in airstrikes after which they were attacked and fought against waves of machine gun fire from NVA forces.

On 8 October 1966, Shriver was operating in the jungle and passing through, two rifle shots were heard nearby and he contacted a supporting aircraft and the teams base that the mission was likely compromised.

Soon after, the security personnel noticed a Viet Cong unit trailing behind and opened fire, injuring one rebel and driving the others from the area.

While commanding a reconnaissance mission deep into enemy-controlled territory on the afternoon of that day, Shriver distinguished himself by acting with extraordinary bravery.

Shriver and his group tried to break contact with the enemy element, which was now the size of a platoon, by giving orders for his members to throw hand grenades so as not to reveal their exact location.

Two USAF gunships were committed by the FAC to provide support, and Shriver oversaw their rockets launched and minigun rounds into the opposing NVA soldiers, which were barely thirty meters apart and preparing for an attack.

During the intense battle, Shriver steadily moved the supporting fire to be within twenty meters of his location until the enemy started to retreat.

[22] For most of 1968, Shriver was still in Vietnam and serving, from January to May he was conducting operations but he took a mandatory leave and returned to the US for the summer.

When Shriver's recon team was placed on a landing strip, they encountered an opposing force believed to be the size of a battalion.

Shriver led his squad of three soldiers and launched a heavy fire attack on the enemy, resulting in four deaths and twenty-six injuries.

[12][16] On April 24, 1969, Shriver and a team of US and Montagnard troops were inserted by helicopter into Kampong Cham province, Cambodia, and came under heavy fire as they approached their initial rallying point.

Subsequent search efforts remained inconclusive, and the Army issued a presumptive finding of his death in 1974.
