The 186th Mechanized Infantry Division was a part of the Star League Defense Force Regular Army.


In the 2760s the Division would rotate its units to cover for other Divisions to allow them to be rotated out of the defensive line.

In 2764 the 186th was a part of XXVIII Corps within the Thirteenth Army and was assigned to to District 3 of the Lyran Commonwealth Military Region. The Division was subsequently moved to an undisclosed area of the Periphery in response to the Periphery Uprising. The Division took heavy casualties in the Periphery Uprising in 2766 causing many survivors to join Amaris' forces in 2767. The Division was officially disbanded at that point.[2]


The commanding officer in 2764 was Major General Conner Stefanopolis.[3]


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.

Composition History[edit]

The Division comprised two Brigades of Mechanised Infantry and a single BattleMech Brigade. Also attached was a Ground Aero Wing.[4]
