[Bill A]

On the DHH lineages page, in the Armoured Branch (Is this the correct designation? Has not the Armoured Branch been re-designated the Royal Canadian Armoured Corps?), some regiments have the supplementary RCAC designation and others don't. Is there a reason for this?
Eg Ontario Regiment (RCAC) compared to the Fort Garry Horse (no supplementary RCAC). Would this be due to the fact that former cavalry regiments do not need the RCAC, while former infantry regiments do?
