The realistic-looking "silver maple" style of leaf (referred to as the "RCAF" roundel) was replaced with the eleven-point stylized leaf of the new Canadian flag in February 1965 (referred to as the "CAF" roundel). A slightly-modified standardized version of this roundel (referred to as the "CAF revision E" roundel) was used by Air Command, and continues to be used by the "new" RCAF. An all-red "unification roundel" was used on a few aircraft from 1967–1968. Like the RCAF roundel, this new roundel sometimes changed – mainly in the size of the leaf and ring thickness, and one version had a white ring, which was used on certain aircraft. The current RCAF also uses a low visibility tactical grey roundel.
