This was followed by the raising of a third battalion at Sarajevo.[6] Only Croats, Ukrainians or White Russians were accepted as volunteers, and about one third of those accepted were Bosnian Muslims.[1] A training battalion was formed for the regiment in Stockerau, Austria. The regiment was then transported to Dollersheim, Austria for training. With an effective strength of 5000, the regiment consisted of three infantry battalions, a machine-gun company, an anti-tank company, three batteries of field artillery, headquarters staff and a supply company.[6]
