The 1st Sussex Artillery Volunteers was a part-time unit of the British Army's Royal Artillery from 1859 to 1961. Raised as coastal defence artillery, the unit later served as field artillery in Mesopotamia during World War I, and in North Africa, Sicily, Italy and North West Europe during World War II. It carried out a number of roles in the postwar Territorial Army.
