ComStar military structure
When ComStar created their own military force, the Com Guards, they diverged from the traditional 4-unit structuring of the Star League Defense Force and later Successor States' militaries by basing their forces on multiples of six. They were further differentiated by using Roman numerals to identify their hierarchical position, from the smallest Level I to the highest Level V. Given their heavy emphasis on combined-arms warfare, the units also use Greek lettering to identify their compositional mix, with those at the beginning of the alphabet containing higher numbers of BattleMechs while those towards the end with larger numbers of conventional forces. When the ComStar Schism resulted in the creation of the Word of Blake, the Blakists copied the same model for their own militia forces.
A Level I is the smallest military unit in the Com Guards/Militia. It consists of a single 'Mech, Aerospace Fighter, tank or artillery piece, or a 36-man infantry platoon. After their introduction, a Level I could also consist of four Battle Armor troopers; this number was later increased to six. Level Is are commanded by Adepts, with Acolytes filling in the roles of enlisted personnel and noncoms.
A Level II, roughly analogous to a reinforced lance or demi-company, consists of six Level I formations. Level IIs are generally the largest unit deployed on low-risk worlds. While normally Level IIs consist of units of the same type, some also contain a mix of forces. Level IIs are commanded by Adepts.

|4 Light, 2 Medium||6 Medium||6 Heavy||3 Heavy, 3 Assault|
|3 Light, 3 Medium||4 Medium, 2 Heavy||2 Medium, 2 Heavy, 2 Assault||2 Heavy, 4 Assault|
|3 Light, 1 Medium, 2 Heavy||3 Medium, 3 Heavy||4 Heavy, 2 Assault||6 Assault|
A Level III, analogous to and commonly referred to as a Battalion, consists of six Level IIs, or a total of thirty-six Level Is. Level IIIs are almost always combined-arms formations, operating together on a regular basis, and the most common formation to be deployed into high-risk areas. Level IIIs can be commanded by an Adept or a Demi-Precentor.
A Level IV consists of six Level IIIs, or 216 Level Is. Though referred to as a Division, it is closer in size to two SLDF-era regiments or a FedCom RCT. Divisions are the largest permanent field unit and form the backbone of the administrative network, however they are rarely deployed intact, instead being scattered across a region to provide defense. The exact area covered by a Division's constituent parts can depend, from a single important world to several dozen. Level IVs can be commanded by a Demi-Precentor or a Precentor.
The below lists gives the approximate proportion of Level I units which can comprise a Division:
A Level V is the largest formation in the Com Guards/Militia, commonly referred to as an Army and commanded by a senior Precentor. At full strength an Army consists of six Level IVs, though for various reasons this has been as few as four, for a total of anywhere from 864 to 1,296 Level I units. Armies are primarily administrative units, although as seen in the Battle of Tukayyid they can also take to the field. Prior to the Schism there were twelve Armies, each one assigned to an area of the Inner Sphere Clock. The threat posed by the Clans and the breakaway of the Blakists have forced the Com Guards to scrap this original arrangement, instead deploying Armies where they are needed. Being too small, the Blakist Militia did not possess any Level V-sized formations up through 3062.
