The 60 pounder gun was used on most fronts during the First World War and replaced the 4.7 inch guns. At the outbreak of war they equipped, with 4 guns, the heavy battery RGA in each infantry division. In 1916 all batteries on the Western Front started being increased to 6 guns. By this time heavy batteries had ceased to be part of each infantry division and batteries became part of what were eventually called Heavy Artillery Groups with several batteries of different types. After the First World War they equipped medium brigades, later regiments.
