St.Kp Gren.E.B.mot.156 EKM (Windhund related)

The dog tag or 'Erkennungsmarke' shows signs of wear. The bataillon was formed in November 1940 in Wuppertal as Infanterie Ersatz Bataillon (motorisiert) 156. It trained and supplied soldiers for the 16.Infanterie-Division. Also known as the Windhund Division. 
In late 1942 the bataillon was renamed into Grenadier Ersatz Bataillon (motorisiert) 156. It still supplied men for the 16.Infanterie-Division. In April 1943 the Ersatz and Ausbildungs bataillons where merged. In June 1944 the bataillon was used to form Panzergrenadier Ersatz und Ausbildungs Bataillon 15 and moved to Kassel. It fell under the command of the Kommandeur der Panzertruppen IX.
A Stammkompanie was a unit that trained the soldiers. Often the soldiers of this kompanie were soldiers who had frontline experience, but no longer were fully usable on the front due to injuries. Of course this changed later in the war and they also where put into action as there was a shortage of (front)soldiers.
