Army ribbons are placed in an order of precedence beginning with personal decorations, then unit awards, service awards, campaign and service awards, service and training awards and marksmanship awards. Ribbons must be worn in this order on an officer's or enlisted man's uniform; they may also be worn on the chests, collars and lapels of civilian dress, but not on recreational clothing or hats.
The order of precedence for Army personnel decorations begins with the Medal of Honor, followed by the Distinguished Service Cross, the Defense Distinguished Service Medal, the Distinguished Service Medal, the Silver Star, the Defense Superior Service Medal, the Legion of Merit, the Distinguished Flying Cross, the Soldier's Medal, the Bronze Star and the Purple Heart. These are followed by meritorious service medals, commendation medals and achievement medals, in that order.
Unit awards begin with presidential unit citations, followed by meritorious unit commendations and efficiency awards. The service awards start with the Prisoner of War Medal, which can be followed, in order, by good conduct medals, reserve decorations and expeditionary medals. Campaign and service medals indicate specific service in different Army campaigns. Service and training awards begin with the Army Sea Duty Ribbon, Army Overseas Service Ribbon and Army Reserve Overseas Training Ribbon, followed by recruiting service ribbons, training service ribbons, guard ribbons and professional development ribbons. Marksmanship ribbons place rifle ribbons before pistol ribbons.
