SLDF Service - Twenty-Fifth Striker Regiment[edit]

In 2763 the Second Regimental Combat Team was sent to the Detroit system to investigate rumors of a build up of weapon stockpiles. The Second was completely unprepared to face a full division of Taurian rebels. The other units of the Second were completely destroyed in the fighting, however the Twenty-fifth managed to fight its way out through the enemy's flanks to escape and call in reinforcements.[1]

In 2764, the unit was assigned, as a part of the LXI Corps, Twelfth Army, to District 2 of the Lyran Commonwealth Military Region, but was moved to an undisclosed area of the Periphery.[2].

Mercenary Service - The Fomorians[edit]

Opting not to join Operation EXODUS to remain in the Inner Sphere, in 2783 the Twenty-Fifth Striker Regiment signed on as a mercenary unit with the Lyran Commonwealth, choosing to call themselves the Fomorians.[3] [4]

Stationed on Eltanin when the First Succession War broke out, the Fomorians were among the many mercenary units to fall during that brutal conflict, being listed as destroyed prior to its conclusion in 2821. [5]
