Headgear is usually what sets apart units in the commonwealth. Certain items are commonplace with all the different countries such as berets, helmets etc. But some also have headgear that is only worn by that particular unit, such as the Aussie bush hat. Commonwealth tankers almost universally wore berets in action until later in the war when steel helmets (where were very similar to the type worn by Airborne troops) were introduced for AFV crews. Aside from that, uniforms were standard, varying pretty much only by the climate and time of year. So yes, British/Commonwealth tankers or armored car crew, such as those by Mini Art, would work.
