AR 670-1: 21-17. Shoulder sleeve insignia-current organization

The SSI is worn on the left sleeve to identify a Soldier's current organization. SSI are authorized for ACOM/ASCC/DRU, armies, corps, divisions, separate brigades/BCTs, separate regiments, and organizations with at least 250-500 military personnel. Soldiers wear the SSI of the unit to which assigned; those in units without SSI wear the SSI of the higher command.
