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.[5]

The Regulars were assigned to Task Force to re-take 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. Occupation force consisting of the 12th Deneb Light Cavalry and Fighting Urukhai were reinforced through the 12th Vegan Rangers Alpha Regiment from Algol, lead by General Ariel Zibler. She directed the attached 27th Federation Tactical Fighter Regiment fend off the Ghosts and Regular's attempts to land on the asteroids of the Al Nair system. However, asteroids themselves destroyed some of FedCom fighter cover, however, 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 land two battalions of ISF special forces route out the 12th DLC's troops from underground complexes. Eventually, Regulars and Ghost had routed out the Davion troops from Al Na'ir by September.[6]


Coordinator Theodore Kurita authorized Combine forces to pursue and punish FedCom forces that took part in the invasion. The Regular's Task Force was then dispatched to Addicks where the unit landed January 24th, 3065.[7]

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 with exhausted after to days of fighting with them and Addick's defenders, Regulars and Ghost withdrew to Al Na'ir.[8]

During the Jihad, the Regulars apparently sided with the Kokuryu-kai rebels, securing Xinyang, Braunton and Dyfed. They were effectively destroyed by the 7th Sword of Light and the Internal Security Force on Xinyang, though some guerrilla action continued.[9] Later reports showed that the 5th Sword of Light was responsible for their destruction.[10]
