War of 3039[edit]

The Fifteenth were stationed on Al Na'ir throughout the War of 3039.[9]

Towne Invasion[edit]

In early 3058 the unit with its supporting regiments, launched an assault on the Federated Commonwealth world of Towne. The invading force, led by the Black Dragon-influenced Jeffrey Kusunoki, he had the support of two newly created Yakuza manned regiments and included the 1st Dragons Joy Infantry. They failed to take the world due to the defensive actions of the mercenary 17th Recon Regiment and local chartered militia forces.[10] The regiment and their supporting units were allowed to retreat of planet with much of their equipment but the Black Dragon units were stripped of all war matériel.[11]

Lyran Alliance Incursion[edit]


In August 1st 3062, the Fifteenth Dieron Regulars fought on Ko against the Lyran First Skye Jaegers, who were seeking revenge for a raid the Regulars allegedly conducted against Skye in July. The Jaegers retreated after they suffered heavy losses, however they took the Fifteenth's salvageable 'Mechs and equipment to slow their rebuilding. It was later discovered that a Periphery mercenary unit posing as the Fifteenth had conducted the raid on Skye. The mercenary unit had been hired by the Black Dragon Society.[12]

Federated Commonwealth Incursion[edit]

Draconis March Incursion[edit]

Al Na'ir[edit]

During the FedCom Civil War, FedCom March Lord, Duke James Sandoval launched an invasion of the Draconis Combine, believing the rogue attack his capital world of Robinson and other worlds on October 18th, 3062.[13]

The Regulars were assigned to Task Force to retake worlds fallen to Duke James Sandoval's forces. In late June in 3064, the Regulars arrived in Al Na'ir shortly being followed from by 10th Ghost in early July. The occupation force consisting of the 12th Deneb Light Cavalry and Fighting Urukhai were reinforced through the 12th Vegan Rangers Alpha Regiment from Algol, led by General Ariel Zibler. She directed the attached 27th Federation Tactical Fighter Regiment to fend off the Ghost's and Regulars' attempts to land on the asteroids of the Al Na'ir system. However, asteroids themselves destroyed some of FedCom fighter cover, within weeks fighting Tai-sa Samuel Noda of 10th Ghost directed Task Force efforts to asteroid known as Yori's Perdition. Though the assault was repulsed, Ghost & Regulars were able to land two battalions of ISF special forces to root out the 12th DLC's troops from underground complexes. Eventually, Regulars and Ghost had rooted out the Davion troops from Al Na'ir by September.[14]


Coordinator Theodore Kurita authorized Combine forces to pursue and punish FedCom forces that took part in the invasion. The Regulars' Task Force was then dispatched to Addicks where the unit landed January 24th, 3065.[15]

On planet, the found uncoordinated and demoralized 12th DLC and its mercenary support force, the Fighting Urukhai. The two FedCom forces had begun resent one another due to loss of Al Na'ir. Regulars and the 10th Ghost launch battalion size waves of troops in rotating basis to wear-down the beleaguered Davion troops. Held up in the Loknair Military Complex, the Davion troops held on for two weeks of Regulars and the Ghost wave assaults against their defenses. The Davion troops held on due for the seizer of supplies from year-long occupation of Al Na'ir. General Zibler order her troops to withdraw from Complex, leaving the Fighting Urukhai alone to defend to complex out revenge.

Regulars and the Ghost at Tai-sa Noda's lead nearly wear out the mercenaries until the Davion Assault Guards arrived on February 13th. Due to now facing the House Davion's most powerful force, along being with exhausted after two days of fighting with them and Addicks' defenders, Regulars and Ghost withdrew to Al Na'ir.[16]


During the Jihad, the Fifteenth apparently sided with the Kokuryu-kai rebels, securing Xinyang, Braunton and Dyfed. They were effectively destroyed by the Seventh Sword of Light and the Internal Security Force on Xinyang, though some guerrilla action continued.[17] While the regiment was effectively destroyed in 3075, members of the Fifteenth were considered to be the most likely suspects behind a wave of mass terror attacks - some using bioweapons - across the Benjamin Military District in 3076 and 3077.[3] Both the Fifth and Seventh Sword of Light regiments were active in working alongside inquisitorial teams of ISF and Order of the Five Pillars personnel to hunt down survivors from the Fifteenth and the First Proserpina Hussars across the Oshika and Xinyang Prefectures before being reassigned to Operation SCOUR.[18]
