War of 3039[edit]

Reinforced Vega in the War of 3039. They joined the 2nd Legion of Vega and the 14th Legion of Vega and fought Snord's Irregulars, the 3rd Davion Guards, and the 1st Grave Walkers. The Second and the two Legion of Vega units were able to drive the Federated Commonwealth forces out of the system.[2] They then returned to their garrison on Cebalrai.[3]

Clan Invasion[edit]

The unit acted as training cadre for other regiments during Operation Revival. They were stationed on Cebalrai in 3050.[4] The commander of the Second petitioned for permission to raid the LexaTech LAM factory on Irece. The Kanrei refused the request because the plant had been destroyed.[5]

Operation Bulldog[edit]

During the Operation the planet Jeanette was liberated through a task force which includes the Second Dieron Regulars, 1st Amphigean Light Assault Group, 1st Aragon Borderers, Warrior House Daidachi and the Crater Cobras. The defending Nova Cat Lancers give the ownership of the planet back to the DCMS after a trial of possession, which they lost. The Second also helped liberate Albiero.

Xin Sheng Campaign[edit]

The Second Dieron Regulars were part of the SLDF peacekeeping force deployed to the St. Ives Compact. They landed on Vesthallas and ordered the defenders to disarm. Aliesha's Mounted Fusiliers and the militia unit refused, and the Second engaged the defending units. They pushed the Fusiliers off of Vesthallas.[6]

Dominion War[edit]

They guarded the border against possible invasions.

Federated Suns Incursion[edit]

The command acted as a reserve unit if the war goes on.


In 3077 the 2nd Dieron Regulars was one of two units to fight alongside Clan Ghost Bear forces on Dieron. Their air wing, the Dragon-kin, was decimated on the way to the planet but the ground units landed with few casualties. That changed when the 2nd Dieron encountered the Word of Blake's 19th Division. The 19th used a Luthien Armor Works facility as their headquarters, and the 2nd Dieron took serious losses breaching the facility's defenses. The Blakists had the last word however, killing most of the 2nd Dieron Regulars command structure when they detonated several nuclear warheads and destroyed the LAW facility.[7]

Later they joined Operation SCOUR as a part of the Draconis Combine front task force[8], saw some combat on Styx in 3077[9] and participated in the assault on Cairo.[10] During the combat drop, Blakist surface-to-air fire destroyed about half the unit. After the Jihad ended, they returned to Dieron.[11]

With the formation of The Republic of the Sphere the Dieron Military District was eliminated. The Second Dieron Regulars were reassigned to the New Samarkand Military District and renamed the 2nd New Samarkand Regulars.[12]

Dark Age Era[edit]

Reformed with the Dieron Military District was officially reborn in 3135, Hopes are high that this new regiment will live up to the famous version of the Second lost in the Jihad era. [13]


In 3145 the commanding officer is Tai-sa Harold Ryan.[16]


The unit specialized in mountain combat, utilizing Light BattleMechs.[17]
