Strange Helmet cover.. raises questions.... in Germany: Imperial: Rick (Research) Lundstrom Forum for Documentation and Photographs Posted August 18, 2018 · Edited August 18, 2018 by The Prussian Hello! I.1 = Bayerisches Garnisons-Bataillon Nr.1 (bavarian garrison-bataillon N° 1) of the first bavarian army corps. Formed June 4, 1915 in Munich. Placed in Rosenheim, used as border and railway protection. The soldiers normally were "garnisonsverwendungsfähig" (usable in garrison) and not "kriegsverwendungsfähig" (usable at war), that means, they were not able to fight at the front, but only serving in the garrison. They also served in POW camps. Note, this man has a Mosin-Nagant M1891 rifle!
