Miscellaneous shoulder sleeve insignia of the United States Army

Shoulder sleeve insignia (SSI) are cloth emblems worn on the shoulders of US Army uniforms to identify the primary headquarters to which a soldier is assigned. Most military units smaller than brigades do not have SSI, but rather wear the SSI of a higher headquarters. Insignia of units that are no longer active can be found at Obsolete shoulder sleeve insignia of the United States Army.
