Sapper, Soldiers who Build, Repair Roads/Bridges as Well as Clear Mines
"If the [Viet Cong] can have sappers....so can we." A sapper, also called pioneer or combat engineer, is a combatant or soldier who performs a variety of military engineering duties such as breaching, demolitions, bridge-building, laying or clearing minefields, field defenses as well as building, road and airfield construction and repair. They are also trained to serve as infantry personnel in defensive and offensive operations. A sapper's duties are devoted to tasks involving facilitating movement, defense and survival of allied forces and impeding those of enemies.
