"I would suggest that SNCOs are far more secure in their staus that they don't feel the need to use them... along with other members of society."
I feel a brief trip through LinkedIn will dispel that notion
In my (recent and extensive) experience of ex-Officers and ex-SNCOs using these items, I reckon the score is about even.
(I speak as ex-both so have no axe to grind, although I do sharpen it every now and then..)
And no, I don't use them - as I ain't got any (sic)!
