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 a military uniform, as specified in Army Regulation 670–1, "Wear and Appearance of Army Uniforms and Insignia." Wearing the tab is permitted for the remainder of a soldier's military career. The cloth version of the tab is worn on the Army Combat Uniform and Class-A dress uniform of the U.S. Army; a smaller, metal version is worn on the new Army Service Uniform.
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.
Marines presented with the Ranger Tab are not authorized to wear it on their uniforms.
