Unit Description[edit]

The Alliance Grenadiers was formed during the Reunification War. They were the sister regiment of the Alliance Borderers and also one of the first five BattleMech regiments to exist within the military command of the Outworlds Alliance.[1] The unit logo is described as two grenades on a white field edged with gold.[2]



The Alliance Grenadiers and their sister regiment, the Alliance Borderers, were formed during the Reunification War, primarily from salvage obtained from Star League forces or equipment purchased covertly from Federated Suns sources. The Grenadiers formed in late 2582 on Alpheratz and first saw combat during the battles for Cerberus, where two battalions of the Grenadiers fought alongside the Cerberus Militia against the the 4th Division and 5th Division of II Corps. Despite the rapid destruction of much of the planetary militia, the Grenadiers fought a guerrilla war that lasted well over a year against the SLDF forces, preventing them from capturing Cerberus.[3][1][4]

The Grenadiers remained on Cerberus until the end of the war in 2585; by the end of the war, the Grenadiers had fought alongside the Santiago Carabiniers, Pitcairn Legion and elements of the 2nd Armored Division against the equivalent of three SLDF divisions.[3]

As a part of the restrictions associated with the status of the Alliance after the declaration of peace in 2585 the Grenadiers were disbanded, but were then reformed later during the Periphery uprising in the 28th century and equipped with 'Mechs seized from SLDF stores within the Alliance. The Grenadiers saw extensive service against pirates among the outer planets of the Outworlds Alliance during the 30th century, although the Grenadiers' two battalions were based on Cerberus and Sevon.[2]

When Chairman Janet Rice took command of the Grenadiers during the Clan Invasion era, the Grenadiers were considered to be a low-morale rabble with little skill. Rice was given responsibility for transforming the Grenadiers back into an effective combat command, something she worked on through a combination of intensive training and new equipment. By the beginnings of the Jihad, the combination of Rice's actions and some battlefield successes during the increasingly frequent pirate raids plaguing the Outworlds Alliance had worked wonders for the Grenadiers' morale, although the regiment was still considered to be a very green formation.[5]

  • Historical: Reunification War indicates on page 42 that the Alliance Borderers received their baptism of fire on Cerberus, against the Star League 4th Division and 5th Division. However, this is contradicted by other entries within the same book for the battles on Cerberus and the unit deployment tables, which indicate that the Borderers fought on Lushann, and that the Alliance Grenadiers fought on Cerberus. This has been raised as errata on the official Catalyst Game Labs forum.[1][4][3]
