The 14th Heavy Battery, Royal Garrison Artillery, was one of the first British Army units recruited for 'Kitchener's Army' in World War I. It served on the Western Front from 1915 to 1918, supporting different formations of the British Expeditionary Force (BEF). It participated in the battles of the Somme and Arras, served on the Flanders coast and against the German Spring Offensive, and took part in the Allies' victorious Hundred Days Offensive. It continued in the Regular British Army postwar.

The 14th (Light) Division was an infantry division of the British Army, one of the Kitchener's Army divisions raised from volunteers by Lord Kitchener during the First World War. All of its infantry regiments were originally of the fast marching rifle or light infantry regiments, hence the title "Light". It fought on the Western Front for the duration of the First World War. The division was disbanded by March 1919, and was not reformed in the Second World War.
