Dog tag with imprint of fingerprint and chain
Metal military identification tag (or dog tag) has two punched holes with a chain attached. One hole is meant for the attachment of a chain and the other is meant for a cloth necklace. On the obverse side of the dog tag, it appears to say "Hahn F.H.," "ENS," "R.F.,"and "3-18-18." It is possible that "ENS" stands for "Ensign" which is a US Naval Rank, "R.F." stands for "Reserve Force," and the date is likely the enlistment date. On the reverse side a fingerprint, presumably the solider's, is stamped into the metal. Though it is not clear if this tag is from the United States Navy, it matches the looks of fingerprint dog tags from the United States Navy from the World War I era.
