Unit Profile (as of 3025)
Nickname Will of the Dieron
Parent Formation Dieron Regulars
Formed unknown


In early 3014 Hanse Davion lead the 34th Avalon Hussars, 10th Deneb Light Cavalry and the Davion Heavy Guards in an attack against the toxic world Halstead Station attempting to destroy the large Draconis Combine supply depot being built there. The defending 9th Dieron Regulars and 2nd Proserpina Hussars regiments failing to stop the destruction of the supply depot still managed to keep all three AFFS regiments tied up until Takashi Kurita could arrive with the fresh 2nd Sword of Light.

As of 3025, the unit's garrison world was Cylene.[1]

Fourth Succession War[edit]

During the Fourth Succession War the Ninth Dieron and Brion's Legion attacked David, facing the 12th Deneb Light Cavalry. They were unable to bring the DLC unit into a stand-up fight. Instead the 12th DLC struck repeatedly at the Ninth's flanks.[2] After a brief lull in the fighting, the Ninth and Brion's Legion were able to constantly maintain contact with the DLC, forcing the AFFS unit into a static fight. Though the Ninth fought well, Brion's Legion broke and ran when their commander was killed. Though the Ninth might have been able to overcome this setback, the arrival of the 41st Avalon Hussars completely altered the Ninth's perspective, and withdrew from the world shortly after the Avalon Hussars arrived.[3]

War of 3039[edit]

During the War of 3039 the Ninth quietly moved off of Cylene and fought their way onto Sadachbia. There they faced off against the 8th Deneb Light Cavalry and Redfield's Renegades.[4] The Ninth performed many hit-and-run attacks on the AFFS units, refusing to engage in a stand up fight. Eventually the Ninth overextended itself and one battalion of the regiment found itself pinned in the planet's spaceport. The DLC and mercenary forces were able to prevent the other two battalions of the Ninth from linking up, and Tai-sa Montgommery chose to preserve her other units. Eventually the isolated battalion was destroyed by the AFFS.

The Ninth continued to perform its signature hit and run style attacks against the Federated Suns commands until they received orders to leave. The Ninth then hit the Deneb Light Cavalry, inflicting serious losses as the unit withdrew from the world.[5]

Clan Invasion[edit]

The Ninth Dieron Regulars were destroyed by Clan Nova Cat forces during the Clan Invasion.[5]


As of 3025, the commanding officer of the unit was General Lisa Montgomery.[6] She committed seppuku for losing one of her battalions in the War of 3039 and was replaced by Tai-sa Mao Sheng-Jo. He led the Ninth until it was destroyed by the Nova Cats.[5]


The unit as of 3025 has no specializations.
