A U.S. Army Sapper tab is only earned by completing a 28-day course at the U.S. Army Engineer School located at Fort Leonard Wood, Mo. The course consists of two 14-day phases, and graduates must meet a set of requirements and goals to earn this badge.
Sappers, sometimes referred to as combat engineers, are one of four Army specializations recognized by a tab; the other three are Rangers, Special Forces and the President's Hundred. Only three of these badges may be worn together by one soldier. Sappers perform a variety of functions that require engineering skills, such as bridge construction, demolition, obstacle rigging and clearance.
The first 14 days of Sapper school consist mostly of learning related skills such as mountaineering, navigation, medical, demolition and weaponry. The second phase focuses more on missions, patrolling and leadership in applied settings. Students are graded on a mix of engineering and infantry missions and must score at least 700 of a possible 1,000 points to earn their Sapper tabs.
