Organization

There are different types of force hierarchies. They are used as a prefix to the unit level to indicate which hierarchy it belongs in.

Imperial (IMP) forces (IMPAIRRON) are formally part of the Imperial Army. Its force hierarchy prefix is only used if other hierarchies are present onworld.

Colonial (COL) forces (COLAIRRON) are raised and funded by the world's population but trained and vetted by the COACC. They are subordinate to Imperial authority, but can command and control any assigned subordinate Imperial assets. They usually are equipped with surplus second-rate Imperial aircraft or whatever the local tech level can produce and support. 

Auxiliary (AUX) forces (AUXAIRRON) are mercenaries that are hired to replace or augment local forces. Their commanders and staff are usually Imperial or Colonial officers unless the mercenary unit has former Imperial Army COACC officers with good service records and enough staff experience. They are usually equipped with obsolete Imperial or paramilitary market aircraft that is usually a few tech levels better than the local industry can produce.
