A sapper, in the sense first used by the French military, was one who sapped (undermined) another's fortifications.
When an army was defending a fortress with cannon, they had an obvious height and therefore range advantage over the attacker's own guns. The attacking army's artillery had to be brought forward, under fire, so as to facilitate effective counter-battery fire. This was achieved by digging what the French termed a 'Sappe'. Using techniques developed and perfected by Vauban, the sapeurs (sappers) began the trench at such an angle so as to avoid enemy fire 'enfilading' (passing directly along) the sappe. As they pressed forward, a position was prepared from which cannon could suppress the defenders on the bastions. The sappers would then change the course of their trench, zig-zagging their way toward the fortress wall. Each leg brought the attacker's artillery closer and closer until (hopefully) the besieged cannon would be sufficiently suppressed for undermining to begin. Broadly speaking, sappers were originally experts at demolishing or otherwise overcoming or bypassing fortification systems.
A sapper is an individual usually in British or Commonwealth military service. Called a combat engineer by the Americans, a pionier by the Germans and a génie by the French, a sapper may perform any of a variety of tasks under combat conditions. Such tasks typically include bridge-building, laying or clearing minefields, demolitions, field defences as well as building, road and airfield construction and repair. In other words, the sapper's tasks now involve facilitating movement of allied forces and impeding movement of the enemy's.
Sapper (abbreviated Spr) is the Royal Engineers' equivalent of Private. This is also the case within the Royal Australian Engineers, where referring to a Sapper as a Private is considered an insult and can result in disciplinary charges being laid.
In France, the civil firefighters and the military firefighters of the Paris Fire Brigade are called "sappers-pumpers" (sapeurs-pompiers, SP): the first fire company created by Napoléon I was a military sappers company. Apart from this, the sappers are the combat engineers.

The Royal Pioneer Corps by comparison provided skilled labour for military construction such as ammunition dumps, trenches, bridges etc workign alongside the engineers.
The US Army authorizes five skill tabs for wear above the unit patch on the left shoulder. Three of these tabs identify soldiers who have passed a course proving their leadership and adaptability: the Special Forces tab, the Ranger Tab, and the Sapper tab, in that order of wear from highest to lowest. The other two tabs authorized are the Airborne tab (worn by airborne units, i.e. 82d, 101st, Special Forces, Special Operations Command, etc.), and the President's Hundred Tab, worn for the best marksmen/women in the Army.
To be a sapper, a soldier must complete the Sapper Leader Course which is operated by the U.S. Army Engineer School at Fort Leonard Wood, Mo. 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, promotable) 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 engineering, cavalry, and infantry soldiers. *. The course is in two Phases.
Phase I lasts 14 days and covers general subjects including medical, navigation, demolitions air and water operations, mountaineering, and land mines and weapons used by enemy forces. Phase II is the remaining 14 days. It covers basic patrolling techniques and battle drills that emphasize leadership. The subjects include urban operations, breaching, patrol organization and movement, and reconnaisance, raid and ambush tactics. It concludes with a three-day situation training exercise, and five-day field training exercise. these missision are a 60/40 mix of engineer and infantry missions.
Leadership is emphasized throughout the SLC. During the course leader roles are rotated regularly and each student is evaluated at least twice on leadership. The results of the Sapper Leader Course are soldiers who are hardened combat engineers who are qualified to fight and lead on today’s battlefields. *.
