The Rosebourg Monarchy has the responsibility of protecting some 200 star systems. This is a great burden for the Legionnaires, as they are tasked to do this with a man-power of some 500 billion Legionnaires. As a result, the Legionnaires are organised and broken down so as to render the whole organisation manageable from the top on down. The Legionnaires are commanded ultimately by the Theatre General of the Royal Legions who is supported by a staff of 010s.

Basic Examples: 1st Squad, 1st Platoon, 1st Sub-Cohort, 1st Cohort, 1st Hover-Armoured Sub-Legion, 1st Legion, 1st Superior Legion of the Grace Minoris Mega-Legion
- Special structures are also instituted during wartime, peacekeeping operations, special detachments to OIP PeaceForce, and other activities.
The Legionnaires have 500 major legionnaire groups - each accounting for around 1 billion soldiers. These are known as Mega Legions. Mega-Legions are identified by the headquarter world of their legion group. Thus, the Mega Legion operating in the vicinity of Grace Minoris is known as the Grace Minoris Mega Legion.
The Mega Legions are then broken down in Superior Legion groups, which account for approximately 200.000 soldiers. Each Mega Legion counts 500 of these Superior Legions. Superior-Legions are identified by a number. Thus, the 1st Superior Legion of the Grace-Minoris Mega Legion could by itself protect one small planet of the Monarchy. A planet with a population of 6 billion and the size of Earth would require approximately 10 of these Superior Legions.
The Superior Legion groups are then broken down even further into Major Legion groups, which account for around 100.000 soldiers. Each Superior Legion group counts 2 of these Major Legion groups. These are likewise identified by a number. Thus, the 1st Major Legion, 1st Superior Legion of the Grace Minoris Mega Legion would be charged with the defence of half of a small planet of the Monarchy. A planet with the population of 6 billion and the size of Earth would require approximately 20 of these Major Legions.
The Major Legion is then broken into two legions - each accounting for 40.000 to 50.000 soldiers. The Legions are again attributed a number. Thus, a legion would be identified as the 1st Legion of the 1st Major Legion of the 1st Superior Legion of the Grace Minoris Mega Legion.
These Legions are then broken into twenty sub-legions - each accounting for around 2.000 soldiers. These sub-legions are identified by the types of units that most compose their ranks alongside a number. So that if armoured hover vehicles are the lead unit, they are considered a Hover-Armoured division. Most of the Legionnaire groups are hover-armoured visions. Thus, a sub-legion would be identified as the 1st Hover-Armoured Sub-Legion, 1st Legion, 1st Major Legion, 1st Superior Legion of the Grace-Minoris Mega-Legion.
This process is repeated until the legions are broken down into small squads.
