The need for dog tags in the U.S. military was brought about with the Civil War. Identifying dead soldiers became a real issue for both the Union and Confederacy alike. Dog tags are of course worn by all soldiers today which provide information such as a soldier’s name, blood type and creed.
Early on in the war and even throughout its duration, soldiers would pin their names and addresses to the back of their uniforms. As the war dragged on, a market opened up for this identification need. . .
Today dog tags are ubiquitous to military life. . .at one time in our nation’s history that was not the case.
