Combat restraints fall into two separate and distinct categories: ( 1) Restraints on the use of particular weapons, such as the prohibitions on the use of dumdum bullets and poison gas; and (2) restraints on the actions that may be taken during the course of combat, such as the prohibitions on the denial of quarter and on the shooting of civilian noncombatants. The discussion which follows will be concerned solely with this latter type of restraints on permissible combat actions.
