 Armor battalions in New Jersey and Vermont were upgraded to M48A1 and M48A3 medium tanks.Between 1975-76 Vermont and New Jersey armor battalions started turning in their M48A3 tanks and began receiving the M48A5 which had the same 105mm gun and fire control system as the M60A1 in use by the active Army.During this time, many Vermont tank crews competed in gunnery exercises held in West Germany and consistently brought back awards.
