Space Services and Pecking order.

Unity Force: Medical aid, goes out after battle. (Like National Guard) Go out when needed for aid and support. Often peaceful and see little to no action. Made of reserves (Volunteers) and retired men and women.

Prime Corpse: Step above Unity force, where beginning Military training commences. (Basically Basic.) Can join Prime at age 16. Basic survival training, basic hand to hand,  and Flight school. (Plus other electives one can take. Bomb Tech., foreign language etc.)

Nova Corpse: Join at age 18, will see some action. Learn to fight in combat situations and combat flight tactics. Military issued weapons training. This is where the Pilots and the ground troops are sorted out. Awards and ability to rise in Rank start here. Mainly work on teamwork and leadership.

The Grand Attack Force: (Like the Air Force for space ships.) Pilots are tested, and given testing to see if they are fit for public service or Combat pilot opportunities. Upkeep, gunnery, flight school, ect.

Public Service Pilot: Those not fit for Combat but still fit for service. They fly the commercial ships and space liners. Postal ship guards etc.

Stealth Fleet: The ones who stand out and become specialists in the Combat pilot area. (Like the seal teem six of Grand Attack.) Those who hold the most promise.

Guardian Space Corpse: (Combination of Marine, Army and Navy) Ground troops, some filtered out due to skill in certain areas. Those that are more aggressive move into one division to train as the front line. Some sent off to work with the ships and more water evaluated missions. Some who are just normal ground troops.

Regulation Force: People in Guardian Space not fit for combat but still fit for service. Police officers, guards, peace keepers.

Warden Vanguard: The over achieving bad asses of bad asses. Specialists, and most potential. (Seal team six, a-team type deal. )

Archangel Defense Force: BIBLE THUMPERS OF SPACE! (VERY RELIGIOUS) Space Templar to say the least. None of them went through the normal channel. (Keeping Military and Religion separate for a reason.) But home to the most powerful healers and medics in the galaxy.

Buster Corps: Bomb Techs, engineers, gunners. If they can't build it or fix it. They can blow it up. Navigators, documentation. (Jack of all trades really, can do everything but didn't really stand out. Mediocre in some situations but excel in war time situations.) Stand out with intellect and sciences.

Ravage Space Service: Junk collectors of space. Mechanics, and traveling trading posts. Normally ex cons and deserters from the Military. But also the most under wired Intel brokers in the galaxy. (The shady con artists.)

Omega: Researchers, scientists, gadget makers for all things military and science. Buster Corps can get into this. The Galaxy most brilliant minds at work. (Also tend to be very abrasive and condescending about their intellect and see all other branches as animals.)

The Executive Grand Council: Group of Presidents from different galaxy. The TOP TOP dogs of the entire universe. Get elected into their seat by the people they represent. Different species and the Archangel Defense Forces' leader has a seat there as well. They decide if they go to war, big decisions and what not.

House of the Councillors: Basically the smaller stuff, like speeding tickets property disputes and court cases. (House Basically in lay mans terms.)
