Reproduction US Army WW 1 Master Sergeant.

Brown wool sewn onto an olive drab wool background.

Size is 3 1/4 x 4 3/4 inches.

War Department notification to AEF American Expeditionary Force, dated 30 April 1918. Rank chevron are only to be worn on right sleeve. So......... in World War 1 "Officially" only a SINGLE chevron was worn on the RIGHT side only. This was done to save material for the war and make it easier for supply.

Listing is for one (1) patch, photo shows front and back.

Thanks for shopping NCHSinc.
