The Sixty-sixth Infantry Division was a part of the Star League Defense Force Regular Army.


In 2764 the Sixty-sixth was assigned, as a part of the XXV Corps, Eighth Army, to District 1 of the Free Worlds League Military Region. While the Sixty-sixth was stationed on the world of New Olympia tensions between the two governments that ruled the planet began spilling out onto the streets, prompting Captain-General Kenyon Marik to deploy the Third Marik Militia to the planet on a peacekeeping mission. The Sixty-sixth was ordered to remain on normal duties by the SLDF chain of command, which viewed the situation as a matter internal to the Free Worlds League. After the Third took casualties during the course of their mission a battalion from the Third lashed out at the Sixty-sixth, apparently out of frustration and resentment over the SLDF remaining inactive during events such as the destructive Marik Civil War. The battalion from the Third attacked a patrol from the Sixty-sixth, prompting the Sixty-sixth to retaliate. The Sixty-sixth nearly destroyed the Third, while Kenyon Marik subsequently claimed that the battalion had gone rogue and had been ignoring orders from the Colonel in command of the regiment. The SLDF Intelligence Command believed that the attack may have been an effort by Kenyon Marik to find a way of waging a covert war against the SLDF.[1]

The Sixty-sixth had been transferred to District 3 by 2765 as part of the redeployment effort to fight the Periphery Uprising.[2] The Sixty-sixth was destroyed during the Hegemony Campaign.[2]


As an SLDF Infantry division the Sixty-sixth would have been formed from two brigades of grunt infantry and a brigade of light BattleMech regiments.[3]
