Galactic Alliance Defence Force

The Galactic Alliance Defense Force (GADF) also known as the Galactic Alliance Armed Forces or the Galactic Alliance military were the military forces of the Galactic Federation of Free Alliances. Like its predecessor, the Combined Defense Forces of the New Republic, the GADF comprised the Galactic Alliance Defense Fleet, Galactic Alliance Starfighter Corps , and the Galactic Alliance Army.

Command
The Galactic Alliance Defense Force was under the overall command of the Supreme Commander, who was appointed by the Chief of State and approved by the Senate. The Supreme Commander, who in keeping with tradition was a full admiral, served as the highest uniformed officer in the Defense Force, answering only to the Chief of State. The GADF mantained its headquarters on Coruscant, in the new Defense Force Command Compound. Presumably Galactic Alliance High Command also had oversight of the Defense Force.

Whilst in theory the Supreme Commander was the ultimate authority on military matters in practise the chief of state was the civilian commander-in-chief and if the chief of state gave an order the supreme commander would follow

Fleet
The naval forces of the GADF was known as the Galactic Alliance Navy, or Defense Fleet. The overall structure of the fleet was modeled on the older New Republic Navy, with five strategic fleets serving as main units of operation for the Alliance. It presumably also maintained static sector fleets, coupled with private planetary navies.

For the first year of the Alliance's existence, the fleets remained fairly unorganized, grouped to individual commanders or assigned to various key worlds, like Kuat, Mon Calamari, Corellia, or Kashyyyk. In the final months of the war, the Defense Force was reorganized into the system modeled after the old Defense Force. Numbered fleets were established, forming a strategic arm of the Alliance military.

Marines
In addition to the fleets, the navy kept marines as ship-to-ship assualt and defence units

Starfighter Corps
The Starfighter corps was seperate from both the navy and the army and held ranks on the level as fleet ranks and army ranks.

Army
Like its forerunner the New Republic Army, the ground forces of the Galactic Alliance were the less glamorous of the three components of the Defense Force, but no less important. Alliance ground forces and commando units played a major role in several ground engagements during the latter portion of the Yuuzhan Vong War, including the capture of Ylesia and the Liberation of Coruscant.
