"We Live to Support"
Distinctive Unit Insignia
A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a buff masoned background bearing a white scroll charged with three horizontal rows of black cipher squares arranged three then six and four squares in base, all between a scarlet scroll folded near each end and inscribed at the top "WE LIVE TO SUPPORT" in gold letters, surmounted overall in base and above the bottom row on the scroll a blue chevron.
The masoned wall represents the location of the original unit, Fort Totten named in honor of Brigadier General Joseph Gilbert Totten, a former Chief Engineer of the Army. The black cipher squares on the white scroll allude to one of the missions of the unit to offer cryptologistic services. The arrangement of the cipher squares, three, six, four symbolizes the numerical designation of the unit. The blue chevron, the color suggested by the background of the State Flag of New York, symbolizes the former Group's authority to provide command and control. Buff and scarlet are colors used by Support units.
The distinctive unit insignia was originally approved for the 364th General Support Group on 20 January 1971. It was redesignated for the 364th Support Group on 15 June 1972. The insignia was redesignated effective 16 September 2009, for the 364th Sustainment Command and amended to update the description and revise the symbolism.
