A recent SOFREP article about military legend Larry Thorne provided a high-level overview of his service in the Finnish military, German military, and U.S. Special Forces. This article provides a more in-depth look at his involvement in Vietnam, and particularly the helicopter crash that led to him being MIA for over 40 years.

Also included below is video footage of Thorne as part of some classic Special Forces Group training, along with a Finnish documentary about his service and accounts from his former teammates.

Larry Thorne: Headquarters Military Assistance Command, Vietnam Detachment SD 5891, 5th Special Forces Group, 1st Special Forces with orders to Studies and Observation Group Long Thanh, South Vietnam. 

Larry Alan Thorne was born Lauri Allan Torni in Viipuri, Finland. As a young adult, he enlisted in the Finish Army where he obtained the rank of Captain. During the early years of World War II, he developed, trained and commanded the Finish ski troops. Under his strict and demanding leadership, the ski troops fought the Russians deep behind enemy lines for extended periods of time. During Finland’s wars against the former Soviet Union, he was awarded every medal for bravery that Finland could bestow including the Knight of the Mannerheim Cross, which is the equivalent of the American Congressional Medal of Honor. After Finland fell to the communists, Captain Torni joined the German SS in order to continue fighting the communists. After World War II, Lauri Torni made his way to the United States where he enlisted in the U.S. Army under the Lodge Bill. After completing basic training, Larry Thorne was selected for the budding Special Forces program. He quickly rose through the ranks, and with the assistance of allies within the military, received a commission. In 1964, Larry Thorne served his first 6-month tour of duty in South Vietnam.

In February 1965, then Captain Larry Thorne returned to Long Thanh, South Vietnam for his second tour of duty. While assigned to Headquarters, Military Assistance Command, Vietnam; Captain Thorne was instrumental in establishing the standard operating procedures employed by the fledgling Studies and Observation Group, better known by its acronym “MACV-SOG.” MACV-SOG was a joint service unconventional warfare task force engaged in highly classified operations throughout Southeast Asia. The 5th Special Forces Group channeled personnel into MACV-SOG (although it was not a Special Forces unit) through Special Operations Augmentation (SOA), which provided their “cover” while under secret orders to MACV-SOG. The teams performed deep penetration missions of strategic reconnaissance and interdiction that were called, depending on the location and time frame, “Shining Brass” “Daniel Boone,” “Salem House” or “Prairie Fire” missions.

When North Vietnam began to increase its military strength in South Vietnam, NVA and Viet Cong troops again intruded on neutral Laos for sanctuary, as the Viet Minh had done during the war with the French some years before. This border road was used by the Communists to transport weapons, supplies and troops from North Vietnam into South Vietnam, and was frequently no more than a path cut through the jungle covered mountains. US forces used all assets available to them to stop this flow of men and supplies from moving south into the war zone.

In September 1965, the infiltration of reconnaissance teams into Laos, Codenamed: “Shining Brass,” was approved, but severe limitations by Washington restricted the teams to penetrate no deeper than 50 kilometers into Laos. In case the team was captured the cover story derived for the first Shining Brass mission was that “they were looking for a crashed US Air Force C-123 cargo aircraft that was lost near the South Vietnamese/Lao border.” Further, in conjunction with planning cross-border missions, Larry Thorne flew as the observer for many intelligence gathering reconnaissance missions over eastern Laos. Because of this, he was very familiar with the entire area in which MACV-SOG’s teams would be operating.

One of the earliest helicopters employed in Southeast Asia, and the primary Marine Corps helicopter used during the early years of the war, was the Sikorsky UH34D Seahorse. This aircraft was already quite old when they arrived in the battle zone. However, both the US and South Vietnamese military found them to be extremely effective throughout the war. The Seahorse was frequently used to insert MACV-SOG teams into Laos.
