These are Perry Miniatures War of the Roses Scurriers, equipped with handguns from the Empire pistolier sprue (although they are so massive they are playing the role of carbines) and more sensibly sized guns from The Assault Group, not too into painting cavalry for unknown reasons, but really like the look of them when they are done.
Ost Averland Dragoner Regiment
Despite this some members of the Averland nobility do join the Dragoons rather then the pistolkorps, appealing to nobles who are desirous of military rank and postings rather then later positions within the Knightly orders. The nature of the Dragoner regiment drawing from commoners and minors nobles means that it is fast growing and has even begun to spread. Neighbouring provinces have begun recruitment for their own Dragoner units.
The Dragoner regiment is equipped with both wheel-lock pistols and carbines. The pistols are much the same as the ones carried by the Pistolkorps, whilst the Carbine is a shortened Musket as used by the Empires Handgunners. This shortened carbine provides gives a greater reach and accuracy than a pistol whilst providing a much greater manageability then the full length Muskets.
The Ost Averland Mountain Garrison maintains a permanent force of the Dragoner Regiment, the mountainous terrain is mostly impractical to horses and renders heavy cavalry useless, but the light horses of the Regiment provide valuable service as scouts and skirmishers. In the mountains the troops will travel mounted and then dismount to investigate crags, slopes, caves or ridges with their horses positioned nearby with a handler in order to facilitate a quick retreat if necessary. Which, as can be imagined, infuriates the un-mounted monsters that dwell in the mountains.
