The Seraph of Man
The Altairian Military operates directly under the Emperor. Any order at any level can be rescinded by said personage. Below the emperor, Generals and Admirals. Ships are organized into fleets, combat groups, squadrons and pairs. Soldiers are in Legions, centuries, cohorts. The XXVI Legion through XXX are composed of non-Altairian troops. The XXXI is composed entirely of adventurers (often retired ones). Currently all the Legions are stationed in Altair as much of the empire has crumbles militarily. The IX is still stationed on Dhakar managing Altair's tenuous hold on that land.
