Stammb.L.A.E.u.A.Abt.34 EKM

The dog tag or 'Erkennungsmarke' shows signs of wear. It belonged to a soldier who served in Stammbatterie Leichte Artillerie Ersatz und Ausbildungs Abteilung 34. The abteilung was formed in Augsut of 1939 in Koblenz as Artillerie Ersatz Abteilung 34. In 1943 the abteilung moved to Trier. It trained and delivered soldiers for Artillerie Abteilung 652 and 11 different Artillerie Regiments. The ersatz part of the abteilung was used to form Kampfgruppe Kastorf and put into action on the Westwall in September 1944. 
A Stammbatterie was a unit that trained the soldiers. Often the soldier of this kompanie were soldiers who had frontline experience, but no longer were fully usable at the front due to injuries. Of course this changed later in the war as there was a shortage of (front)soldiers and where mobilized also.
The 'B' on both parts of the tag stands for the bloodtype of the soldier. This was carved in by the soldier himself.
