Erkennungsmarken and Soldbuch
On the first day of
mobilisation in August 1939 all serving members of the German armed forces were
issued with Erkennungsmarken or identity tags.
German ID tags were made
from a number of metals. Early war tags, such as the ones worn by Das Heer members
were made of aluminium whereas later on zinc and finally steel were used.
German tags never carried
the name of the owner on them. They carried a number issued by the unit he was
in at mobilisation they also carried the abbreviation of the unit above the
number. These tags were issued by company sized units.
For troops called up after mobilisation the tag would bear the details of
their Ersatz or replacement unit and not the unit they eventually served
in. This tag stayed with the owner throughout their service even if they
transferred to another unit so it was vital that unit records were kept up to
date.
