Green beret
U.S. Special Forces wear the green beret as a distinction of excellence and uniqueness within the Army.
10th Special Forces Group (United States)
The green beret was authorized for wear by Col. William E. Ekman, the group commander, in 1954, and it became group policy. By 1955, every soldier in the unit wore a green beret as part of the uniform. However, the Department of the Army (DA) did not recognize the beret as headgear. The DA banned the wear of the beret, but it was later restored by President Kennedy, a major champion of the Special Forces.
