The Italian cockade appeared as green-white-red or red-white-green interchangeably, and rudder stripes were likewise applied in either order. Fuselage cockades came into general use in 1918, shortly after the adoption of the symbol on wings. Throughout the entire war, Italian markings display tremendous variation in design, size and position.
