|Parent Formation||Lyran Regulars|
Star League Era
The regiments of the Lyran Regulars were prone to being disbanded and reactivated as needed; each time a regiment was reactivated, it would be populated with a mix of re-enlisted veterans and fresh recruits, before being assigned to a garrison posting to free up a line regiment for active service. During peacetime, the Regulars would then disband down to a much smaller size as a brigade, awaiting the next time they would be called on. During the closing decades of the Star League era the First carried the nickname "The Officer Regiment", a consequence of the number of personnel assigned to the regiment as a result of being under-performing leaders that the Lyran Commonwealth Armed Forces felt might be capable of filling secondary officer positions within line regiments during a crisis. Critics of the First pointed out that appointing officers who weren't underachievers to command positions within the First might result in the production of some better officers now, rather than inferior officers in the future.
The First Lyran Regulars were subsequently reformed during 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. 
Fourth Succession War
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. 
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 Third Lyran Regulars, the Fourth Donegal Guards and 40 conventional regiments in an assault on Harvest. They were opposed by the Fifth 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.  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.  In May 3029 the First was deployed to The Edge to reinforce the Tenth Donegal Guards, who had been in the process of conquering the planet when the Twenty-fifth Rasalhague Regulars had counter-attacked and left the Guards stalemated close to Bono, the planetary capital city. The First dropped north-west of Bono and began advancing on the city, quickly clashing with the planetary militia. The militia responded with booby traps and suicide charges that caused a breakdown in cooperation between the BattleMech and conventional elements of the First, but which were insufficient to stop the First from pushing forward through superior numbers. By mid-July, the First had reached the outskirts of Bono, giving the Tenth an opportunity to make their own attack. Coordinating their attacks, the two Lyran RCTs pressed forward, with the Tenth crossing the minefields and defensive positions the Twenty-fifth had prepared during the lull even as the First broke through the defensive fortifications ahead of them before moving into Bono's industrial park.
With a dominating victory in sight, the First Lyran Regulars 'Mech forces slipped, changing course to chase down a 'Mech company from the Twenty-fifth and leaving the Second Vulcan Mechanized Infantry Regiment exposed. The Twenty-fifth capitalised on that error, throwing forces at the Second Vulcan and using the opportunity to break for their DropShips. Even as the Twenty-fifth abandoned The Edge, a botched recognition sign between the Lyran regiments on the ground led to a blue-on-blue incident that cost them a 'Mech and twenty dead infantry, but the Commonwealth had secured The Edge.
War of 3039
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. 
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.

- 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.  This implies a relation to Ostola Stellwar, even though the elder Stellwar was not the First's commander of note at the time.
