 When the army formalised chevrons as rank insignia for their non-commissioned officers, quartermaster sergeants were given the insignia of a down-pointed chevron of worsted braid above the elbow of each arm in the same colour as the buttons of the regiment or corps.Although the Continental Marines did not have quartermaster sergeants, the U.S. Marine Corps introduced the rank when it was established, initially having only one quartermaster sergeant who was attached to the corps headquarters (like all NCOs above the rank of sergeant).The rank was in use by both the Union Army and the Confederate Army during the American Civil War.
