21st Arcturan Guards
|Twenty-first Arcturan Guards|
|Unit Profile (as of 2765)|
|Parent Formation||Arcturan Guards|
The Twenty-first Arcturan Guards was founded after the initial founding of the Arcturan Guards brigade, and in common with the later-founded regiments, didn't bear a name based upon a Muse from mythology.
Star League Era
Like the other regiments of the Arcturan Guard, the Twenty-first struggled with boredom and ennui during the closing years of the Star League era; the Star League Defense Force acted as an effective deterrent in the main, making large-scale military deployments for the Twenty-first a rarity, and leaving the regiment to occupy itself with training exercises and garrison duty.
Critics of the Twenty-first in the mid-2760s complained that the Twenty-first's posting to the world of Borghese was a case of family connections - namely those of the commanding officer, Colonel Hassan Steiner-Owalt to get his unit assigned on an extended vacation. Officially, the Twenty-first was stationed on Borghese to focus on "blue-water" operations.
