A Wound Chevron was a United States military insignia authorized for wear on the service uniform between 1918 and 1932.
It denoted wounds which were received in combat against an enemy force or hospitalization following a gassing.
However, it was rescinded by Paragraph 1(d) of War Department General Orders Number 6 of January 12, 1918, which replaced it with wound chevrons.
This was not required, however, and some Army personnel elected to retain wound chevrons for wear on their uniforms instead of the Purple Heart.
The decoration is very similar to the Overseas Chevron, which in World War I was worn on the left sleeve.
