Military ranks are a system of hierarchical relationships, within armed forces, police, intelligence agencies or other institutions organized along military lines.

It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command constructs an important component for organized collective action.
