The Mechanised Infantry Divisions of the Star League were used offensively to exploit gaps in the enemy front created by the BattleMech Divisions. They also bore the brunt of defensive actions.

The Division comprised two Brigades of Mechanised Infantry and a single BattleMech Brigade. Also attached was a Ground Aero Wing.[2]
