Lauri Allan Törni (28 May 1919 – 18 October 1965), later known as Larry Alan Thorne, was a Finnish soldier who fought under three flags: as a Finnish Army second lieutenant of the Fourth Independent Jäger Infantry Battalion against the Red Army in the Winter War and the Soviet-Finnish sub-theater of World War II known as the Continuation War; as a German Army captain (under the alias Larry Lane) of the Finnish Volunteer Battalion of the Waffen-SS when he fought the Red Army on the Eastern Front in World War II; and as a United States Army Captain (under the alias “Larry Thorne”) when he served in the U.S. Army Special Forces in the Vietnam War.
Törni died in a helicopter crash during the Vietnam War and he was promoted to the rank of major posthumously. His remains were located three decades later and then buried in Arlington National Cemetery; he is the only former member of the Waffen-SS to be interred there.
