Description
A scarlet quatrefoil edged with a red 1/8 inch (.32 cm) scarlet border, 2 3/8 inches (6.03 cm) in width and height overall, a black grape leaf centered thereon.

Symbolism
The four lobes of the quatrefoil represent the four states of which the original unit was composed, Maine, Vermont, Rhode Island and Connecticut. Red indicates that the states were originally English Colonies. The grape leaf signifies that the New England country was the vineland of the Norsemen whose history goes back to the year 1000.

Background
The shoulder sleeve insignia was originally approved for the 43d Division (designated the 43d Infantry Division in 1942) on 15 March 1923. It was redesignated for the 43d Command Headquarters (Divisional, Connecticut National Guard) on 16 October 1963. The insignia was redesignated for the 43d Infantry Brigade with the description and symbolism revised on 1 September 1993. It was cancelled effective 30 September 1997, when the Brigade was redesignated as the 143d Support Group. (TIOH Dwg. No. A-1-107)
