The Grand Army of the Republic is broken up into two divisions - Army and Navy, both with similar ranking structures and served primarily by clones bred on Kamino for ten years and trained for war. This makes the Grand Army a fearsome sight on the battlefield with its numerous identical warriors in clone trooper armor.
The clone army forms the core of the ground forces of the Galactic Republic, equipped with similar armour, modified for the most part simply to denote rank. Pure-white armour is for a regular clone trooper, olive-green for the clone sergeants, blue for clone lieutenants, red for clone captains and yellow for clone commanders, in ascending rank order. Nine troopers make up a squad, led by a sergeant. Four squads make a Lieutenant-led platoon, four platoons make a captain-led company and four companies make up a commander-led regiment. Using their ion blaster rifles, clone troopers are a fearsome, unified sight on the battlefield. Occasionally, clones might see fit to make use of a 74-Z speeder bike as rapid land transport.
Of course, there are other kinds of clone troopers - such as the crack-trained ARC Troopers and clone commandos, plus clones outfitted for all kinds of terrain - SCUBA Troopers being the primary modification. Others with difference in training and equipment also exist - clone pilots, clone lancer troopers and clone jet troopers being some of the most prevalent.
Heavy Surface Vehicles
The attack units of the Republic are numerous and deadly. The most common of these are the All-Terrain Tactical Enforcer, a walking tank that is reputed to be able to even scale a cliff and bombard an enemy with its myraid guns. Supporting this is the Self-Propelled Heavy Artillery, the TX-130 fighter tank, the All-Terrain Recon Transport and the All-Terrain Open Transport. Known for their tough armour and heavy guns, the Republic's vehicle choice is an extension of their combat style - hard and relentless.
Air Support And Starfighters
The Republic's choice of aerial vehicles is relatively small, but what they do have packs an immense pucnh. The most famous of these is the Low Altitude Assault Transport, and its three variants - Infantry, Carrier and Vehicle. Starfighter classes, like the aerial vehicles, are small in variance but are strong - mainly deployed currently are the V-19 Torrent and the Delta-7 Aethersprite, while the first ARC-170s are just coming off the assembly lines.
The primary Republic warship is the Acclamator-class, coming in both the Acclamator I and Acclamator II classes. Serving also are the venerable Dreadnaught cruisers, CR90 Corvettes and the two new and experimental ships Victory-class Star Destroyer and Venator-class Star Destroyer.
Ranks in the Republic military are simple: The Army and Navy follow near-on identical rank structures with only six ranks, with colours assigned to most ranks. White denotes the Army's Private and Navy's Midshipman. Olive green shows the Army's Sergeant and the Navy's Ensign. The next three ranks are identical across both services - blue for Lieutenant, red for Captain and yellow for Commander, in ascending order. Finally, no colour is assigned for the army's General or the Navy's Admiral, the highest ranks attainable.
