During the latter 19th Century and early 20th Century, the auxiliary forces (each of which had its own order or precedence: Yeomanry order-of-precedence; Militia order-of-precedence; Volunteer Force order-of-precedence) in the UK were increasingly integrated with British Army units, while maintaining separate force hierarchies. In the process, they were removed from the control of the Lords-Lieutenant of Counties and administered directly by the War Office. The only point of distinction between a British Army unit and an auxiliary, whether in the UK-proper or a colony, was whether or not it was wholly or partly funded by the War Office (from Army funds). As Militia Tax and other funds were replaced for UK auxiliary units, they were added to the British Army order of precedence. Although most auxiliary units had in 1881 (after the Cardwell and Childers Reforms) become companies or battalions of regular army corps or regiments, they were not grouped with their regular companies or battalions in the British Army order of precedence. Instead, each entire force was added separately to the order of precedence of the British Army, with its respective units retaining their original orders of precedence within that (where the force contained units
