Detachment 101 of the Office of Strategic Services (formed under the Office of the Coordinator of Information (COI) just weeks before it evolved into the OSS) operated in the China-Burma-India Theater of World War II. On 17 January 1956, it was awarded a Presidential Distinguished Unit Citation by President Dwight Eisenhower, who wrote: "The courage and fighting spirit displayed by its officers and men in offensive action against overwhelming enemy strength reflect the highest tradition of the armed forces of the United States."[1]
Detachment 101 was "the first American unit ever assembled to conduct guerrilla warfare, espionage and sabotage behind enemy lines."[2]
