WW2 US Army 5th Service Command SSI Shoulder Sleeve Insignia

The WW2 US Army 5th Service Command SSI (Shoulder Sleeve Insignia) is a cloth insignia worn by personnel assigned to the 5th Service Command during the Second World War. The 5th Service Command was established to direct administrative and logistical support for Army units in a multi-state region of the United States, primarily focusing on training, supply, and personnel management functions. The insignia typically features a blue lozenge bordered in red, bearing a white number “5” at the center, which denotes the command number. Constructed of embroidered cotton or wool, these patches were designed for display on the upper left sleeve of the Army uniform. The SSI served both to identify unit affiliation and to foster organizational esprit de corps. The 5th Service Command played a significant role in the home front military effort, particularly in organizing resources and support for active field units during the war.
