The Vietnam War Missions of This Special Ops Group Were So Secret They Weren't Officially Revealed Until the 1980s

You may be familiar with the renowned US Navy SEALs and the US Army's Green Berets, both known for their expertise in guerrilla and counter-guerrilla tactics, as well as their roles in training local forces and countering insurgencies during the Vietnam War. However, it's crucial not to overlook the vital contributions of MACV-SOG, which skillfully combined personnel from these elite units with CIA agents. Together, they formed a formidable secret force that executed covert missions with high-levels of success throughout the war.

The mission of MACV-SOG encompassed many unconventional warfare efforts in Vietnam, including reconnaissance, daring rescue operations, psychological warfare, and the capture of enemy combatants. Their efforts strongly impacted the trajectory of the war.

MACV-SOG's top-secret beginnings

On January 24, 1964, MACV-SOG, officially known as the Military Assistance Command, Vietnam - Studies and Observations Group, came into existence. Comprised of operators from the most elite branches of the US military, including Green Berets , Navy SEALs , Air Force Commandos, CIA operatives and veterans of the Marine Corps' reconnaissance units, the group was an assembly of specialized talent.

Initially, MACV-SOG's operations in Vietnam were overseen by the Special Assistant for Counterinsurgency and Special Activities within the US Department of Defense . This arrangement granted the authority to conduct missions beyond the borders of South Vietnam. Eventually, control of the group was transferred to the military.

A significant portion of MACV-SOG's missions occurred within North Vietnam, and the utmost secrecy was imperative. This discretion was necessitated by the official American stance that the US forces were confined to operations within South Vietnam. Additionally, the group dedicated efforts to missions in Laos and Cambodia, due to the strategic significance of the Ho Chi Minh Trail, which played a crucial role in supporting the North Vietnamese Army (NVA).

Given the exceptionally perilous nature of their tasks, MACV-SOG was exclusively composed of volunteers. The hazardous conditions were so pronounced that the casualty rate for operatives stood at a staggering 100 percent; they understood their service would likely culminate in either receiving a Purple Heart for their valor or returning home in a flag-draped casket.

Unidentifiable Americans

Due to the classified nature of their missions, MACV-SOG adhered to specific uniform guidelines designed to make them indistinguishable as Americans. They wore the distinctive tiger stripe camouflage commonly associated with the South Vietnamese and refrained from displaying any form of identification, including dog tags and patches. Similarly, the Green Berets chose not to wear their identifiable headgear.

Regarding weaponry, MACV-SOG typically used either a CAR-15 or AK-47 , along with M79 grenade launchers . Notably, the serial numbers of these weapons were removed to prevent identification. Each weapon was carefully secured to the individual in a manner that minimized any potential noise from their movements. Guns were carried with a canvas strap, while the M79s were attached using a D-ring covered in tape.

In addition to firearms, operators carried supplementary weapons, including fragmentation and V40 mini grenades. This choice of weaponry was as unconventional as the missions they undertook. An illustrative example is Staff Sgt. Robert Graham, a MACV-SOG member who opted for a 55-pound bow equipped with razor-edged arrows, using it when conventional ammunition became scarce.

Ho Chi Minh Trail

The primary theater of action for MACV-SOG was the Ho Chi Minh Trail due to its importance for the guerrillas they were up against. In this region, the group played a crucial role as ground operatives, collecting intelligence for Saigon. Their tasks involved taking photographs, seizing enemy documents, and intercepting communication lines.

These missions were extremely risky, and those assigned to them received significant assistance from local forces, who made up the bulk of a unit. Generally, two to four Americans would work alongside four to nine South Vietnamese guerrillas.

In an interview with History of MACV-SOG , Jim Bolen discussed the complexities of conducting missions along the Ho Chi Minh Trail, emphasizing that each mission took place along the network's essential paths. These routes were frequently bordered by large enemy camps that housed thousands of soldiers.

These challenges were exemplified by missions such as the one on Thanksgiving Day 1968 , when a six-man team faced off against an enemy force of 30,000. Another instance was Frank D. Miller's lone encounter with 100 NVA troops.

MACV-SOG operations behind enemy lines

During an interview with the History of MACV-SOG , Jim Bolen disclosed that he and his team were assigned the duty of deploying seismic sensors along the Ho Chi Minh Trail. These sensors were monitored by Lockheed C-130E Blackbirds, providing early alerts of important enemy movements.

It is widely acknowledged that thanks to this and other intelligence-gathering endeavors, MACV-SOG played a key role in providing 75 percent of American intelligence on the Ho Chi Minh Trail.

Additionally, MACV-SOG pursued another objective during their missions along the Ho Chi Minh Trail: conducting operations to apprehend prisoners behind enemy lines. These missions were seen as one of the most dangerous tasks and could be either a primary or secondary objective, depending on the circumstances. Nonetheless, such operations received strong support from commanding officers.

Prisoner snatching behind enemy lines

Members of MACV-SOG were incentivized with a reward of $100 for each captured enemy soldier, as well as the promise of rest and relaxation (R&R). Local allies were rewarded with new watches and varying amounts of cash. This incentivization strategy proved effective, leading to several successful captures, such as 12 soldiers in Laos in 1966. These yielded valuable intelligence on enemy troop movements, sizes and base locations.

Capturing prisoners demanded inventive tactics from MACV-SOG operatives. Lynne Black , an operator, meticulously calculated the precise amount of C-4 required to incapacitate a target without causing fatal harm, a process undoubtedly fraught with trial and error. Operatives strategically placed explosives along trails, patiently awaiting the approach of enemy troops before remotely detonating the C-4. This method enabled them to swiftly extract their unconscious targets.

Throughout the Vietnam War, MACV-SOG played a pivotal role in numerous significant engagements, including Operation Steel Tiger, the Tet Offensive, Operation Tiger Hound, Operation Commando Hunt and the Easter Offensive. Despite their skill, their involvement in the conflict remained largely undisclosed until the 1980s.

It wasn't until 2001 that the group's members were formally recognized, with them receiving the Presidential Unit Citation.
