wearer's ship or unit are worn with naval combat dress. Air Force personnel may be authorized to wear squadron ball caps with CADPAT or flying suits when on the flight line or aboard ship as part of a ship's helicopter detachment. Berets The beret is still the most widely worn headgear, and is worn with almost all orders of dress with the exception of the more formal orders of Naval and Air Force dress (i.e. Ceremonial, Mess, and Service Dress). A regimental or branch cap badge is worn centred over the wearer's left eye, and excess material pulled to the wearer's right. The colour of the beret is determined by the wearer's environment, branch, or mission. The beret colours listed below are the current standard: History Berets were first worn in the Canadian Army in 1937 when tank regiments (at that time part of the infantry) adopted the black beret of the Royal Armoured Corps. The black beret, which is now the headdress of the Royal Canadian Armoured Corps (RCAC), was first worn by the Essex Regiment (Tank), now renamed The Windsor Regiment (RCAC). This was because the other new tank units were ordered to wear the headdress that they had while serving as infantry. The Essex Regiment (Tank) was a new unit, formed as a tank regiment, with no connection to the Infantry. As such, it picked the headdress that was worn by the Royal Tank Corps of the British Army. During the Second World War, a khaki beret was adopted throughout the Canadian Army, with the Canadian Armoured Corps (later Royal Canadian Armoured Corps) wearing the black beret and parachute troops wearing the maroon beret adopted by British airborne forces. The 2nd Canadian Parachute Battalion (the Canadian component of the First Special Service Force) wore a red beret with the dress uniform. Wartime berets were much fuller in cut than postwar berets. After the Second World War, a series of coloured berets were adopted, with infantry regiments wearing scarlet, rifle regiments wearing dark (rifle) green, the armoured corps wearing black, and other arms and services wearing midnight blue berets, with a large coloured "flash" in corps colours - dull cherry for the Royal Canadian Army Medical Corps, Emerald Green for the Royal Canadian Dental Corps, etc. The coloured flashes were not popular and replaced in 1956 with forage caps bearing coloured bands in corps colours.
