Society Military Structure

The Prime system is the main military structure used by Society cells. The smallest formation in the Prime system was the Un, which included 1-7 armored units (or three platoons of infantry). Three Uns formed a Trey, the smallest formation deployed independently, albeit very rarely. Two Treys working together under a command Un formed a Sept. The Society typically deployed one to two Septs on independent missions, while a single Sept or a group of up to four independent Treys were often assigned to augment corrupted Coyote forces. Corrupted Coyotes themselves did not use the Prime system, retaining the Clans' original system.

Unit	Formation Size	Information
Un	1 BattleMech, 3 Battle Armor troopers, 3 conventional infantry platoons, 3 ProtoMechs, 3 AeroSpace Fighters, 7 Combat Vehicles	The smallest Society formation, roughly equivalent to a Clan Point.
Trey	3 Uns	The smallest formation deployed independently, albeit rarely. Has no direct Clan equivalent.
Sept	7 Uns (2 Treys + 1 Command Un)	The largest formation formally recognized in the Prime system, roughly equivalent to a Clan Star.

Notes

• The Prime system is designed such that all BattleMech formations result in formation sizes that are prime numbers (1, 3, 7). Other unit types include prime numbers as part of their Un-level formation size. Despite appearing before 7 in a series of prime numbers starting from 1, no formations include 2 or 5 units (though this is likely to maintain parity with BattleMech formations, and to distinguish Prime from the Clan system which regularly uses quantities of 2 and 5).
• Under the Prime system, the Society is the only notable faction to field AeroSpace Fighters with a smallest-formation size other than 2. Society and Capellan Confederation armed forces both field their Flight-equivalents in groups of 3.
