In Korea, 'gunbeonjul' refers to a military ID chain, known as 'dog tags' in English. These chains have ball-shaped links and are used for identification in the military. Created mostly from stainless steel, they are resistant to corrosion but may wear over time due to sweat exposure. The name dog tag originates from the similar design of pet identification tags. Historical uses of ID tags date back to ancient Sparta and Roman soldiers. The tags serve crucial roles in wartime for identifying soldiers; with one tag attached to the deceased and another returned for record purposes. Fascinating anecdotes and legends surround gunbeonjul, but they remain essential for identification.
