had a system of coloured bayonet knots that identified the wearer's company, number shoulder strap buttons that identified the wearer's company/battalion, and shoulder straps that identified the wearer's regiment, but had no distinguishing divisional insignia other than the cuff titles of the 'elite' formations. The British Army prohibited all identifying marks on its
Battle Dress uniforms in 1939 save for drab regimental slip-on titles, but in 1941 introduced formation patches to identify the wearer's division. They were initially referred to by the British as "Divisional Signs", but this was soon changed to "
Formation Badges". By the end of the war,
Corps, Armies, and Army Groups had their own insignia.

[ Law, Clive M. ''Distinguishing Patches: Formation Patches of the Canadian Army'' (Service Publications) ]
The United States continued its system as shoulder sleeve insignia with a regulation that prior combat service entitled the wearer to sew the formation patch of a former unit on the right sleeve of a uniform or field jacket, and the patch of the currently assigned formation on the left sleeve.
Modern usage
Formation patches have survived into the 21st Century in many modern militaries, though when in use on combat uniforms are generally rendered in subdued colours and their use in their original intended purpose - battlefield identification - is questionable.
