Training Frisky - that's two.
Well let's see.
You're quite right, on reflection I don't think I ever have worn a squadron badge on my flying kit. I do remember though on my Winter Survival course at Bad Kolgrub that the instructors advised that they should not worn on operations - and I was buggered if I was going to keep putting them on and taking them off.
I did wear one badge though. It was a great big thing with a red swan on it I think. Long time ago now but I remember myself and the rest of the staff at CFS used to call it "chicken in a basket"
