Just a quick one.... Does anyone know how qualified you have to be to be promoted to SGT? what I mean is as far as I can tell if there are no time restraints ie your due it, you can pick up without having completed an sclm (parts 1 and 2) so long as you pass it within a year (please do tell if I'm wrong). Also does this rule aply across all trades? Apparently its different for techs??
