The uniforms of the British Army currently exist in twelve categories ranging from ceremonial uniforms to combat dress (with full dress uniform and frock coats listed in addition). Uniforms in the British Army are specific to the regiment (or corps) to which a soldier belongs. Full dress presents the most differentiation between units, and there are fewer regimental distinctions between ceremonial dress, service dress, barrack dress and combat dress, though a level of regimental distinction runs throughout. Senior officers, of full colonel rank and above, do not wear a regimental uniform (except when serving in the honorary position of a Colonel of the Regiment); rather, they wear their own 'staff uniform' (which includes a coloured cap band and matching gorget patches in several orders of dress). As a rule, the same basic design and colour of uniform is worn by all ranks of the same regiment (albeit often with increased embellishment for higher ranks). There are several significant uniform differences between infantry and cavalry regiments; furthermore, several features of cavalry uniform were (and are) extended to those corps and regiments deemed for historical reasons to have 'mounted status' (namely: the Royal Artillery, Royal Engineers, Royal Corps of Signals, Army Air Corps, Royal Logistic Corps and Royal Army Veterinary Corps). British army source the uniforms with different suppliers, mostly from their colonies in the past. Full dress Full dress is the most elaborate and traditional order worn by the British Army. It generally consists of a scarlet, dark blue or rifle green high-necked tunic (without chest pockets), elaborate headwear and other colourful items. It was withdrawn from a general issue in 1914, but is still listed in the Army Dress Regulations, which speaks of it as "the ultimate statement of tradition and regimental identity in uniform" and the "key" to all other orders of dress. Each regiment and corps has its own pattern, approved by the Army Dress Committee. They are generally a modified version of the pre-1914 uniforms. In the case of units created since the First World War, such as the Army Air Corps, the Full Dress order incorporates both traditional and modern elements. Gloves as worn with Full Dress uniform are white for all ranks in all regiments and corps, with the exception of The Rifles, the Royal Gurkha Rifles, the Royal Army Chaplains' Department, and the Royal Irish Regiment, who all wear black gloves in Full Dress.
