A little old but still I think fairly interesting: The Canadian Army is reviving various traditions including the Pips and Crown which are integral to our military heritage and our strengthening the British Connection. Stephen Leacock would be so pleased!
It seems that there is a possibility of doing so for the Royal Canadian Air Force as well...
According to Peter MacKay: "We're looking at a number of ways in which we can continue to restore historic symbols, ranks, insignia that respect the history of the Canadian Forces," he said. "So specific to the Air Force ranks, we'll look at it. this is consistent in keeping with what was stripped away and taken from the Canadian Forces in 1968 by a previous government".
For Guards Regiments they are even using the Order of the Garter insignia!
