The 16th Field Battery was an Australian Army Reserve unit based in Tasmania with depots at Paterson Barracks in Launceston and Derwent Barracks in Hobart until 2013, when it was reduced in size to a troop, and amalgamated with its Adelaide-based sister battery, 48 Field Battery, to form the 6th/13th Light Battery. The unit is the oldest artillery unit in the Australian Army, and the longest continually serving unit in Australia. Like the rest of 9 Brigade, 16 Troop's force generation cycle is now aligned with that of the Australian Regular Army's 1st Brigade (based in Darwin).
