A dog tag is the informal name for the identification tags worn by military personnel, named such as it bears resemblance to actual dog tags. The tag is primarily used for the identification of dead and wounded and essential basic medical information for the treatment of the latter, such as blood type[1] and history of inoculations, along with providing religious preference. Dog tags are usually fabricated from a corrosion-resistant metal or alloy such as aluminum, monel or stainless-steel, although, during wartime, they have been made from whatever metals were available. In the US military, if the member has a medical condition that requires special attention, an additional, red tag with the pertinent information is issued and worn with the dog tags.
