The Combat Service Identification Badge (CSIB) is a metallic heraldic device worn on the right pocket of the United States Army's Army Service Uniform that uniquely identifies a soldier's combat service with major U.S. Army formations.
The Combat Service Identification Badge is worn centered on the right breast pocket for male soldiers and on the right side parallel to the waistline for female soldiers. Soldiers can wear the CSIB on the new blue Army Service Uniform, Class A and Class B. The CSIB can be worn on the current Dress Blue Uniform until it is phased out in October 2014. The CSIB cannot be worn on the Army Combat Uniform (ACU) or the Army Green Uniform. Soldiers will continue to wear the Shoulder Sleeve Insignia-Former Wartime Service on their right sleeve of the ACU to denote combat service, as well as on the Army Green Uniform, until that uniform is discontinued in October 2014. The CSIB is ranked fifth in the order of precedence for identification badges.
