Description
On a shield arced at top and bottom 3 inches (7.62 cm) in height and 2 inches (5.08 cm) in width overall and divided horizontally blue and gray, a pair of white bayonets in saltire below a white crescent, all within a 1/8 inch (.32 cm) light blue border.

Symbolism
Blue and white are the colors used for Infantry, which indicate the unit’s origin, and the bayonets allude to the mission and combat readiness. The crescent, taken from the State Flag of South Carolina, and the colors blue and gray refer in part to the history of the State and the Militia who in 1775 on James Island, "showed up in blue uniforms with a silver crescent on their caps.” The crescent is also used to represent the unit's allotment to the Army National Guard of South Carolina.

Background
The shoulder sleeve insignia was originally approved for the 218th Infantry Brigade on 3 June 1974. It was redesignated effective 1 September 2008, for the 218th Maneuver Enhancement Brigade with the description and symbolism updated. (TIOH Dwg. No. A-1-577)
