Planetary Security Forces
Planetary Security Forces are one part gendarmerie, one part military reserve force. They are used to protect the worlds they are stationed on from both criminals, since in an interstellar society some criminals, including pirates can be powerful enough to threaten an entire world, as well as from enemy invasion during wartime. Sometimes Planetary Security Forces are used for planetary assaults, or reinforce allied worlds but generally only when their parent governments need them in a war situation. While reserve forces are usually the most numerous amongst Planetary Security Forces, more resources are usually devoted to their roles as auxiliary police forces and planetary defenses.
