Planetary Defense Force

The Planetary Defense Force is a planets first line of defense against raiders, local threats such as revolutions, and alien or AI assaults against a planet. A Planetary Defense Force's assets are greatly varied due to the wide variety in resources and infrastructure that a planet has. More important systems will have large fleets with excellently equipped ground forces that rivals the High Imperial Army, while others have only a few thousand troops armed with the most basic of weapons. If a Planetary Defense Force is unable to defend itself from the enemy (Planetary Defense Forces are rarely able to defeat an extraterrestrial threat), the planetary ruler will call for the High Imperial Army and Navy to assist in defending their planet. If there are any forces available to send, they will be sent to assist the Planetary Defense Force. Many times though, a Planetary Defense Force will have been wiped out before their reinforcements can arrive.
