The Ranger Tab is a service school military decoration of the United States Army signifying completion of the 61-day long Ranger School course in small-unit infantry combat tactics in woodland, mountain, and swamp operations. It is currently one of four permanent individual skill/marksmanship tabs authorized for wear by the U.S. Army. In order of seniority, they are the President's Hundred Tab, the Special Forces Tab, the Ranger Tab, and the Sapper Tab. Only three may be worn at one time. U.S. Marines and Airmen presented with the Ranger Tab are not authorized to wear it on their uniforms.
