99th Infantry Division Patches

99th Infantry Division shoulder sleeve insignia.

By World War II, all army groups, field armies, corps, and divisions, as well as all major Army commands,
had unique Shoulder Sleeve Insignia or SSI. The 99th Infantry Division was also called the “Checkerboard”
division, which gained its nickname from the division’s insignia. The insignia was invented during the division’s formation in 1942,
in the city of Pittsburgh.

The design is a three lined checkerboard design of blue and white squares centered on a black shield.
was adopted from the coat of arms of William Pitt for whom the city of Pittsburgh was named. The black background represents the iron district of Pennsylvania.
