Mark with US Army Shoulder Sleeve Insignia: 323rd | #402045

The United States Army is one of the three military departments (Army, Navy and Air Force) which reports to the Department of Defense. The modern US Army has its roots in the Continental Army, which was formed on 14 June 1775. A shoulder sleeve insignia (SSI), is an embroidered patch worn on some uniforms of the United States Army. Unit tabs are an integral part of the SSI and are never worn separately. The Band Tab is worn by an Army band within a given unit. This is the 323rd Army Band Tab.
