The 174th Field Regiment was a unit of Britain's Royal Artillery (RA) during the Second World War. Originally formed to man beach defence batteries, it was later converted to field artillery. It served in Home Forces and supplied trained gunners to the fighting fronts, but saw no active service. It was disbanded in 1943.

The 55th Infantry Division was an infantry division of the British Army's Territorial Army (TA) that was formed in 1920 and existed through the Second World War, although it did not see combat. The division had originally been raised in 1908 as the West Lancashire Division, part of the British Army's Territorial Force (TF). It fought in the First World War, as the 55th Division, and demobilised following the fighting. In 1920, the 55th Division started to reform. It was stationed in the county of Lancashire throughout the 1920s and 1930s, and was under-funded and under-staffed. In the late 1930s, the division was reduced from three to two infantry brigades and gave up some artillery and other support units to become a motorised formation, the 55th Motor Division. This was part of a British Army doctrine change that was intended to increase battlefield mobility.
