AS CIC officer, here what is tell to my cadet...
winter = toque if training outside (since toque is standard issue)
Spring, Autumn = either safari hat, or beret depending what is done and in late Autumn...toque
having a head gear is mandatory.
It the wish to wear some other toque...its OK as long as they are not wearing the combat uniform.
The olive green combat uniform or cadpat may be worn if it is a complete uniform (boots, pants, shirt, coat, slippon or arm band)
If they miss a part...well it is to bad for them
as for the sleeve...it is permitted to be rolled on summer, on hot day during may-June exercise.
during normal training at the unit, combat is no allowed. It either their uniform, PT, or civilian depending of the activities and it is determined by the C/CWO according to the unit CO recommendation.
