YT, me neither, indeed virtually none from ITS either. I remember on who got bonus points for being a hard B as cadet parade cdr. Don't really remember any on my nav course from ITS either.
Of my nav course, two ex Cranditz Navs (they came to 1 ANS to complete nav training). Most went trucks and when Argosy, Beverley, Britannia etc all went so did the navs.
