Dog Tag
01
Personal identification tag used by troops.
Named "dog tag" after the permit worn on dog's collars.
Approximately 5cm in size, often made of aluminum or stainless steel. Stamped with the owner's full name, date of birth, gender, blood type, military branch, rank, serial number, and religion.
Worn so that, as long as the dog tag is found, a soldier's corpse can be identified.
