Dog tags is informal, however, commonly used term for identification tags used by soldiers. The name “dog tags” originated due to their similarity to animal registration marks. Stamps were primarily used to identify dead and wounded soldiers. Nowadays, they are also wear as a jewellery. Dog tags contain personal information about soldiers and also provide basic medical information such as a blood group, or some armies mention or for example, the history of vaccination. Dog tags also often indicate religious preferences.
An important feature of dog tags is that they are made of corrosion resistant metal. The dog mark usually consists of two identical stamps on one chain or one that can be simply divided into two parts. This duplication allows anyone to take one or half a tag from the body of a soldier for reporting the death and the other remains with the body for identification when the war conditions prevent the transport of mortal remains.
