Dog Tags

A dog tag is the informal name for the identification tags worn by military personnel, because of their resemblance to actual dog tags. The tag is primarily used for the identification of dead and wounded along with providing essential basic medical information for the treatment of the latter such as blood type and history of inoculations. Dog tags are usually fabricated from a corrosion-resistant metal or alloy such as aluminum, monel or stainless-steel, although during war-time they have been made from whatever metals were available.
