The figures dont represent any particular unit. Purists might shudder at the mix of uniforms and equipment, but I enjoy the somewhat ragtag appearance. My rationalisation for their appearance - if asked - is that towards end of the war the German forces were suffering from massive supply and manpower problems, and looked anything but uniform. And besides, the SA 6th Armoured Division fought such a mix of German forces (ranging from elites like the Fallschirmjager Divisions, the Herman Goering Division, and the 5th Mountain Division, through veteran Panzer and SS divisions, and Lehr Battalions, to reluctant Osttruppen and garrison divisions) that there is no way to represent them all. So I would rather build a "generic" force that could be used to proxy any of them.
These then, although painted a while back, are a selection the most recently completed Heer figures. Most of the infantry are Artizan, with a few additional specialists from Warlord.
