In order to help collectors & re-enactors complete their impressions the correct way, I thought it might come
in handy to say a few words about Identification Tags, aka Dog Tags worn by U.S. Army personnel during World War II .
Several ‘groups’ and ‘specialists’ had specific prefixes on their
Identification Tags and, while dealing with the subject, I think a few more
notes on “Dog Tags” in general, would also help … as you know the sole purpose
of wearing Dog Tags is to enable positive identification of a casualty or remains, and to make a difference both for
families and authorities, should the person end up as being known but to God !

The Identification Tag was first introduced December 20, 1906 by General Order No. 24 which described it as follows: “… an aluminum Identification Tag, the size of a silver Half Dollar, stamped with the name, rank, company, regiment, or corps of the wearer; it will be worn by each Officer and enlisted man of the Army whenever the field kit is worn; it will be suspended from the neck, underneath the clothing by means of a cord or thong passed through a small hole in the tag; it is further described as being part of the uniform …” this tag will be issued by the Quartermaster Corps gratuitously to enlisted men and at cost price to the Officers !

ARMY SERIAL NUMBERS
Army Serial Numbers (ASN) are part of an official
designation, and will appear in every military record, in which the name of the
holder appears, i.e. in all documents – so, special care should be taken that
the correct ASN be used at all times, since certain records are filed this way,
and payments and/or allowances are often settled by Army Serial Number, and not
by name – it is always used by servicemen, and, trust me, almost every Veteran
still remembers his individual Army Serial Number …
