A human shield is a non-combatant who either volunteers or is forced to shield a legitimate military target in order to deter the enemy from attacking it.

The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention colloquially denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone.
