Since November 28, 2001, the black beret is worn by all United States Army troops unless the soldier is approved to wear a different distinctive beret. In the U.S. Army there are three approved distinctive berets. On June 13, 2011, the Army announced that the patrol cap will replace the black wool beret as the default headgear for the Army Combat Uniform. The maroon beret has been adopted as official headdress by the Airborne forces as a symbol of their unique capabilities, the tan beret by the 75th Ranger Regiment, and the green beret by the Special Forces.
