Planetary defense force

A planetary defense force refers to the military directly governed by a local government rather than the Unified Earth Government. Planetary defense forces are distinct from the United Nations Space Command and Colonial Military Authority.

Spartan Operations, a service branch of the United Nations Space Command armed forces, recruits veteran personnel from select planetary defense forces. Some planetary defense forces utilize F-41 Broadswords.
