List of Named Units of Fhainnin Armies

National Army (1925-1946)
After the 1925 Constitution, the PRA underwent major reforms and an expansion of its numbers. The previous sixty-four divisions were expanded to one hundred, and later to 114, with a planned 120 by the end of 1935. Most of these were infantry reserve divisions, with a core of forty specialist and mechanized/armored divisions. During the reforms, units were organized with numbering from 1-100, with constituent units using a decimal system (such as 1.1.1 being 1u Division, 1u Brigade, 1u Ceitern).

Collaborationist Units
After 1935, a number of volunteers and vetted POWs from conquered territories were employed as rear-line units and auxiliary forces. This includes the Revolutionary Republics of the Eastern and Northern Gaels as well as the Companainn, who served directly under the National Army rather than a collaboration government. Revolutionary Republican troops were organized under the umbrella of 'ARSG Joint Forces Command', which effectively served as a Regional Command composed of collaborating forces.
