Back in '75 I was with the C Scot R at Milcon in Ft Lewis Wa. We happened to be there on Canada Day, and paraded in S4B in the main part of the base. I still remember the shock and awe from the US soldiers a couple of days later when the local base paper printed a photo of A Coy's CSM...
The Picture was a head and shoulders shot of the man (whose nickname amongst the troops was "Mad-Dog"), but really all you could see was teeth, tonsils and uvula, because his mouth was wide open. The caption read something to the effect of "What I want is dressing, and I want it right bloody now".
We heard many comments about it fm various US types we ran into. I don't think they were prepared for anything approaching a Commonwealth CSM.
