Army Sapper Tab, metal

To be awarded the Sapper Tab, a service member may or may not hold the military occupation specialty code (MOS) designation as a Combat Engineer (Sapper), but must have graduated from the Sapper Leader Course(SLC), that the U.S. Army Engineer School at Fort Leonard Wood, Missouri, operates. The school falls under the 169th Engineer Battalion, 1st Engineer Brigade.
The Sapper Leader Course is a 28-day course designed to train joint-service leaders in small unit tactics, leadership skills, and tactics required to perform as part of a combined arms team. The course is open to enlisted soldiers in the grades of E-4 (P) (in the Army, specialist on the list for promotion to sergeant) E-5, and above, cadets, and officers O-3 (Army, captain) and below. Students can come from any combat or combat support branch of the service, but priority is given to engineer, cavalry, and infantry soldiers.
The tab is currently one of four permanent individual skill tabs (as compared to a badge) authorized for wear by the U.S. Army. In order of precedence they are the President's Hundred Tab, the Special Forces Tab, the Ranger Tab, and the Sapper Tab. However, only three tabs may be worn at one time (not including tabs that are part of the shoulder sleeve insignia such as Airborne or Mountain).
