Organisation of the Imperial Army

These are the units of the Imperial Army.

Unit types
Imperial Army units are separated into two broad categories, local and imperial.

Local
Local units are units that recruit from a planet's native population, and are headquartered and primarily located on that planet. They are thus comprised of troops from a single planet and typically a localised geographical area. Local units are not usually deployed on interplanetary or expeditionary actions, though may be called upon as forces are required. Local units are more numerous than Imperial units.

These forces are responsible for defending their home planets, as well as maintaining order and Imperial rule over their jurisdictional areas on these planets. They also maintain the balance of power between the provinces by intervening in inter-provincial wars or put down local rebellions.

Imperial
Imperial units are units that recruit from multiple planets, with most imperial units' top-level headquarters located on Yamatai. While they may be deployed onto certain planets during garrison periods, the imperial-type units are comprised of troops from all over the Empire. They are also regularly deployed from planet to planet on peacekeeping, anti-insurgency, expeditionary or other activities. Some imperial-type units are not garrisoned on planets, and instead await combat on patrolling assault fleets.

While there are less imperial units than local units, imperial-type units make up the main offensive forces of the Imperial Army and tend to be trained to a higher standard than their localised counterparts. With little personal ties to local areas, the troops of imperial units are thus ideal for dealing with uprisings or localised conflicts.

Army group
The army group is the largest organisational unit in the Imperial Army, a self-sufficient combat force comprising of several armies and including support forces such as naval or aerial forces. Army groups usually have around 700,000 troops in total, spread across at least 5 area armies.

An army group is commanded by a Marshal General.

Area army
An area army is commanded by a General.

Division
Divisions typically include between 9,500 to 14,000 personnel. A division is commanded by a Lieutenant General.

There are two main types of land divisions in the Imperial Army, infantry and armoured divisions.
