sappers
Military demolition experts
Sappers are military engineers who specialize in fortification, demolition, and obstacle clearing.
The term comes from digging saps—trenches that approach enemy positions.
Modern sappers build bridges, clear minefields, and breach defenses: Sappers moved ahead of the infantry to neutralize booby traps.
In some armies, all combat engineers are called sappers regardless of specific duty.
