Unit Composition of the Inner Sphere

The unit composition of the Inner sphere has been basically unchanged over the four centuries of constant warefare. The basis of the units found in the inner sphere are as follows:

House Units/Mercanaries
Single unit / squad (1 mech / vehicle, 1 aerospace figher and1 infantry squad)
Lance / Plattoon (4 mechs / vehicles, 2 aerospace fighter and 4 squads of infantry or 21-30 infantry) =4 units
Company (12 mechs/vehicle, 6 aerospace fighter and 63-90 infantry) = 3 lances
Battalion (36 mechs/vehicle, 18 aerospace fighter and 189-270 infantry) = 3 companies
Regiment (108 mechs/vehicles, 54 aerospace fighters and 567-810 infantry) = 3 battalions

As for the clans, the structure are of 5 units as a star.

1 point (1 mech, 2 aerospace fighters or 5 elementals)
1 star (5 mechs, 10 aerospace fighters or 25 elementals) = 5 points
1 binary (10 mechs, 20 aerospace fighters or 50 elementals) = 2 stars
1 trinary (15 mechs, 30 aerospace fighters or 75 elementals) = 3 stars
1 cluster (60 mechs, 120 aerospace fighters or 300 elementals) = 4 trinaries
1 galaxy (240 mechs, 480 aerospace fighters or 1200 elementals) = 4 clusters
