Stamm-Battr.Art.Ers. Abt.26 EKM (Belgium)

The tag or 'Erkennungsmarke' shows normal signs of wear. It belonged to a soldier who served/was drafted in the Stamm-Batterie Artillerie Ersatz Abteilung 26. The abteilung was formed in September of 1939 in Düsseldorf. It trained and delivered soldiers for Artillerie Regiments 26, Artillerie Regiment 147 and for Artillerie Abteilung 233. In Juli 1941 the Abteilung was moved to Spa, Belgium where it was used as an occupation force. In October 1942 the abteilung was split in an Ersatz and a Reserve Abteilung. The ersatz abteilung was then moved back to Germany as where the reserve abteilung moved to the Channel Coast.
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 'A' on both parts of the tag stands for the soldier's bloodtype.
