On a red shield arched at the top and base 3 inches (7.62 cm) in height and 2 inches (5.08 cm) in width overall, three vertical yellow arrows pointed upwards encircled by a yellow band all within a 1/8 inch (.32 cm) red border.
The three arrows are used to allude to missiles and the three main Ryukyu Islands of the unit's former home station. The dual band symbolizes a specific area (target), and also simulates a zero which, in conjunction with the three arrows, suggests the numerical designation of the organization.
The shoulder sleeve insignia was originally approved for the 30th Artillery Brigade on 12 April 1966. It was redesignated for the 30th Air Defense Artillery Brigade on 4 April 1972. The insignia was amended to update the description and symbolism on 14 June 2012. It was amended to correct the description on 28 May 2013. (TIOH Dwg. No. A-1-417)
