The Four Hundred Twenty-eighth BattleMech Division or the Concordance Division was a part of the Star League Defense Force Regular Army.[1]


The 428th formed a part of LXVII Corps, Twentieth Army, and in 2764 was stationed on an undisclosed world within the Rim Worlds Republic Territorial State. The 428th suffered heavy losses during the Periphery Uprising in 2765 and the division was disbanded as a result; some elements of the division joined the rebels.[1]


As an SLDF BattleMech division the 428th would have been formed from two brigades of BattleMech regiments and a brigade of mechanized infantry regiments.[2]
