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.
Those graduating from Ranger School are presented with the Ranger Tab, which is worn on the upper shoulder of the left sleeve of the Army Combat Uniform, as specified in Army Regulation 670–1, "Wear and Appearance of Army Uniforms and Insignia." A smaller metal version of the tab is worn on the Army Service Uniform. Wearing the tab is permitted for the remainder of a soldier's military career. It is currently one of four permanent individual skill/marksmanship tabs (as compared to a badge) 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.
