The Army Service Uniform (ASU) is a military uniform for wear by United States Army personnel in garrison posts and at most public functions where the Army Combat Uniform is inappropriate. As of 2021, the Army has two service uniforms for use by its personnel. The Army Green Service Uniform, announced in 2018 and authorized in 2020, is used primarily for daily use in situations where civilians wear business attire, such as office settings or official meetings.
The Army Blue Service Uniform, which was the sole service uniform between 2015 and 2020, is used primarily as a dress uniform for ceremonial occasions or formal social situations. Over history, a number of different non-combat service uniforms have been authorized by the Army.
