Parent Formation Lyran Regulars

The 1st Lyran Regulars was a BattleMech regiment in service to Lyran Commonwealth and relatively briefly to the Federated Commonwealth.



The First Lyran Regulars were formed shortly before the Succession Wars from a mercenary unit known as "The Boomers". The members of this unit entered House Steiner's permanent service in exchange for fiefdoms and titles. [1]

As of 3025, the First was based on Romulus. [2]

Fourth Succession War[edit]

In 3026, the First Lyran Regulars were one of many Lyran regiments reorganized by Archon Katrina Steiner into Regimental Combat Teams, based on the successful model used by the Armed Forces of the Federated Suns. [3]

When the Fourth Succession War broke out in 3028, the First Lyran Regulars were part of the largest invasion by the Lyran Commonwealth against the Draconis Combine in over a century. Joining the 3rd Lyran Regulars, the 4th Donegal Guards and 40 conventional regiments in an assault on Harvest. They were opposed by the 5th Amphigean Light Assault Group and the mercenary regiment Hannibal's Hermits, as well as 20 conventional regiments. Using the AFFS' "Lightning Company" tactics, the First Lyrans won a stunning victory against the Fifth Amphigean at the Battle for Dangalobee Fields, creating havoc in the enemy's rear. [4] The DCMS troops were soon forced to withdraw, leaving Harvest for the Lyrans.

The First later took part in a successful attack on Verthandi, taking that world as well. [5]

War of 3039[edit]

The First Lyran Regulars effectively sat out the War of 3039, garrisoning Ridderkerk. [6]

Clan Invasion[edit]

As of early 3050, the First Lyran Regulars RCT were based on Maestu in the Tamar March. [7]

Later that year, when the Clan Invasion struck the Federated Commonwealth, the First had moved to Ridderkerk, and were one of the few AFFC units in position to blunt the opening thrusts. Clan Wolf's 328th Assault Cluster landed on Ridderkerk in July 3050. Unfortunately for the Boomers, their commanding officer, Hauptmann-General Jane Craigie was in a coma as a result of a traffic accident, and the unit's second-in-command was unable to effectively mobilize the defenders. Lacking even the coordination and leadership to retreat offworld, the First Lyrans were entirely destroyed in less than a day of fighting. [8][9]


In 3025, the First Lyran Regulars were commanded by Leutnant-Colonel Ostola Stellwar. [2]

In 3050, the First Lyran Regulars RCT were led by Hauptmann-General Jane Craigie. [7] The unit was commanded by Leftenant General Ostola Stellwar on Ridderkerk.[9]


Under Archon Katrina Steiner's reforms, the First Lyran Regulars not only implemented the combined-arms approach taken by all RCTs, they also employed "Lightning Companies"; lighter, swifter 'Mechs that could take advantage of weaknesses in an enemy's formation, inflicting serious damage behind his lines. [4]

Composition History[edit]

  • CO: Leutnant-Colonel Ostola Stellwar


1st Lyran Regulars RCT (Veteran/Reliable)[6]


1st Lyran Regulars RCT (Veteran/Reliable) [7]

  • CO: Hauptmann-General Jane Craigie


  • Field Manual: Lyran Alliance states that Tellam Stellwar, who later commanded the entire Lyran Regulars brigade, lost his father when the First was destroyed on Ridderkerk. [10] This implies a relation to Ostola Stellwar, even though the elder Stellwar was not the First's commander of note at the time.
