As previously stated, the Cpl rank insignia with the top chevron bisected by the maple leaf is an early version of the CF Combat rank. It is actually the second version of corporal's rank for the combat uniform. The first version worn by the Army from 1963 to C1967 was two plain chevrons. The second version with bisected top chevron was worn from C1967 to C1972. The first version was reintroduced and was worn until the adoption of Cadpat.
