@Cernel actually the current set up is more historically accurate the US basically had an official color (olive drab) for everything but naval units in ww2. so troop uniforms vehicles and aircraft

this color is basically what we r using now for US in most maps.
italy on the other hand had a mix grey green or light grey green for troops and vehicles, ash grey with red and white stripes for naval vessels and kind of all over the map for aircraft.
