Commands were notionally of Army level, some choosing army command colours (red and black) and in the U.K. in the early years of the war could command one or more corps as 'Corps districts'.[45] In Southern Command (United Kingdom) the colouring of the shield and sometimes the stars was varied according to the wearers arm of service, 18 second world war varieties are known including the headquarters, and the Auxiliary Territorial Service.[46]

The corps formation sign would be worn by headquarters and any attached troops, that is, those not in a division, independent infantry or armoured brigade, an Army Group Royal Artillery or a lines of communication formation. After the B.E.F.'s return from France, existing and newly formed Corps (I - XII) were allocated districts, and known as 'Corps districts', under the existing Home Commands, as shown below. They were replaced by military districts during 1942 and 1943.[52] Not shown are VI Corps, based in Northern Ireland and VII Corps based around Oxfordshire and Gloucestershire, neither had a formation sign as a real formation and both were disbanded before the end of 1940.[53][54]

The appropriate arm of service strip would be worn below the sign on a uniform (see above), with the exception of some (service) corps in I Corps, which altered the colours of the diamond as appropriate. For example, engineers (two diagonal blue stripes on the diamond),[55] signals (a blue diamond),[56] artillery (diamond halved vertically, blue and red)[57] and service corps (diamond halved horizontally blue on yellow).[58]

The Canadian and Australian uniform signs shown below are the headquarters signs.
