Stamm-Kp Gren.Ers.Batl.484 EKM

The dog tag or 'Erkennungsmarke' shows signs of wear. The soldier of the tag served in the Stammkompanie Grenadier Ersatz Bataillon 484. The bataillon was formed in November 1939 as Infanterie Ersatz Bataillon 484. This bataillon trained and supplied soldiers for the 254.Infanterie-Division. In November 1942 the bataillon was renamed in to Grenadier Ersatz Bataillon 484. In May 1944 the ersatz bataillon was disbanned and the soldiers were absorbed in Ersatz- und Ausbildungs-Bataillon (M) 276. 
A Stammkompanie was a unit that trained the soldiers. Often the soldiers of this kompanie were soldiers who had frontline experience and/or where no longer 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.
The 'A' on the tag stands for the bloodtype of the soldier.
