The Air Force Staff Sergeant Rank (SSgt) is the lowest Non-Commissioned Officer (NCO) rank in the US Air Force, but is a highly sought-after rank non-the-less. This rank is the first promotion within the US Air Force awarded on a competitive basis. The pin design includes three silver chevrons outlined in blue with an encircled star in the center, with an additional curved chevron below the encircled star to differentiate from the SrA rank. This rank pin is sold as a pair with a pin clutch backing and is 100% made in the USA. The pin measures 1 1/8 inches.
