The Prometheorg Military is based on a model that has worked for ARMOR for nearly 200 years. The ARMOR military has three branches: Infantry, Armor, and Air Force. All units fall within the three branches, with no overlap. As such, they don't have any real use for Robots (which they view as blurring the lines between Armor and Infantry) or SAMAS-type power armors (which they view as blurring the lines between Armor and Air Force). They do use power armors, which are relegated to the ranks of Infantry, and sky cycles, which are part of the Air Force.
The Prometheorg Military does have a few unique units that were brought with it from the other timeline. The vehicles that were brought with the ARMOR forces include the Ram Battletank, IFV, Terran Fighter, and the ARMOR Heavy Cruiser. The most important unit brought over from the other timeline is the terrifying Terrine Bio-Gen Warrior. Bio-Engineered to fight on Earth, the Terrines are ruthless and brutal in their methods.
The Infantry of the Prometheorg Military consists of the Terrine Bio-Gen Warriors and the support Olympic-class power armor. The Infantry also uses the Rhino Infantry Fighting Vehicle and a version of the Lynx hoverjeep for transport purposes. The smallest unit of the Infantry is the squad. A squad usually consists of 2 Olympic-class powerarmors, 7 Terrines, and a squadleader of Sergeant rank. 4 Squads form a platoon, led by a Lieutenant. 2 Platoons form a Lance led by a Captain. 4 Lances form a company, led by a Major. 2 Companies led by a Lt. Colonel form a Battalion. 2 Battalions, or 4 Companies, form a Regiment, led by a Colonel. 2 Regiments, plus a support Company and a headquarters Company, forms a Brigade, led by a Major General. A full General will command an Army, usually consisting of 2 or 3 Brigades.
Besides the Terrine Infantry of the army, ARMOR also utilizes infantry units composed of regular humans and Combat Gennies. The human units are stationed primarily in the area around Norfolk-GAW and also assist in peacekeeping assignments in and around the various towns and cities. The Combat Gennie units are used primarily as bodyguards and security forces, with an emphasis towards Special Forces training. Both units fulfill those duties not usally suitable for Terrine units.
The Armor Brigades of the Prometheorg Military consist of the Ram Battletank and the heavy-weapon version of the Lynx hoverjeep. The smallest unit of the Armor is also a Squad. A Squad will consist of 4 Ram Battletanks and a Lynx hoverjeep. An Armor Platoon consists of 5 Squads. An Armor Company consists of 4 Platoons. 2 Armor Companies form a Battalion. An Armor Regiment consists of 2 Battalions. An Armor Brigade consists of 2 Armor Regiments, a headquarters Company, and a Scout Company of Lynxes. The highest unit of Armor is the Corps, consisting of 2 or 3 Brigades. Armor unit ranks are the same as those for the Infantry.
The Air Force of the Prometheorg Military consists of the ARMOR Terran Fighters, the ARMOR transport shuttles, and the ARMOR Battlecruisers. The smallest unit of the Air Force is the Flight. A flight consists of either 2 Terran Fighters or 2 transport shuttles led by a Flight Leader. 10 Flights form a Squadron, led by a Commander. 4 Squadrons form a Wing, led by a Captain. 2 Air Wings led by a Lt. Colonel form an Air Battalion. 2 Air Battalions, or 4 Wings, form an Air Regiment led by a Colonel. 2 Air Regiments, plus a ground support company and a ground headquarters company, form an Air Brigade, led by a Major General. A full General commands the Air Army, which consists of 2 or 3 Air Brigades or nearly 2000 fighters.
