In the United States Army, tabs are cloth and/or metal arches that are worn on U.S. Army uniforms, displaying a word or words signifying a special skill. On the Army Combat Uniform and Army Service Uniform, the tabs are worn above a unit's shoulder sleeve insignia (SSI) and are used to identify a unit's or a soldier's special skill(s) or are worn as part of a unit's SSI as part of its unique heritage. Individual tabs are also worn as small metal arches above or below medals or ribbons on dress uniforms.

The Sapper Leader Course is a 28-day United States Army small unit tactics and leadership course that develops soldiers in critical skills and teaches advanced combat engineer techniques needed across the Army. Sapper training began development in 1982, and continued until 1985. The course is broken down into two, two-week phases, General Subjects, and Patrolling. The Sapper Leader course is often seen as the engineer equivalent to the US Army Ranger School, a school traditionally associated with and attended primarily by light infantry soldiers.
