Demoralization is, in a context of warfare, national security, and law enforcement, a process in psychological warfare with the objective to erode morale among enemy combatants and/or noncombatants. That can encourage them to retreat, surrender, or defect rather than defeating them in combat.

A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with telescopic sights. Modern snipers use high-precision rifles and high-magnification optics. They often also serve as scouts/observers feeding tactical information back to their units or command headquarters.
