A shoulder sleeve insignia (SSI) may be authorized for organizations listed in paragraph 28-16, AR 670-1 and for other organizations with at least 500 military assigned. A request for SSI should include a copy of the permanent orders activating the unit and a mission statement if the unit is TDA. TIOH will prepare a proposed design and forward it to the unit for concurrence. After the unit commander approves the design, TIOH will prepare a manufacturing drawing and authorization letter for the insignia.
