The regiments of the Andurien Cavalry brigade serve as the Duchy of Andurien's rapid reaction forces.
The brigade was established in 3095 with the founding of the First Andurien Cavalry. As the Duchy in previous years had annexed several nearby independent systems, the Andurien Cavalry were created by Duchess Evelyn Humphreys to address the resulting overstretch of the Andurien Defense Force. Intended to allow the Andurien Guards to focus on defense and the Andurien Rangers to carry out various other missions, the Andurien Cavalry were tasked with serving as the rapid reaction force of the ADF. Highly mobile, the Cavalry would respond swiftly to any incursions or pirate raids too large for militia to handle. 
The First Cavalry proved so effective at countering piracy and occasional raiding from neighboring states that a second regiment was added to the Cavalry in 3101. Shortly after, however, the First Cavalry was destroyed in an assault on Fronde during the Victoria War and never rebuilt. The Second, on the other hand, acquitted itself well on Claybrooke and ensured that the new brigade would not be folded into the Andurien Rangers. Instead, in the years after the Victoria War, the Andurien Cavalry grew into an integral part of the ADF.  
The Andurien Cavalry became proficient in fast response on both an interstellar scale and on battlefields, and at countering trouble spots during multi-regiment operations. The HPG Blackout and resulting lag in communications proved a hindrance to the Cavalry performing their primary mission.
