I thought that all ORs started off as troopers once they'd been badged? Is that correct? It must be financially damaging to pass selection as (say) a CSgt and get dropped to the bottom rung. That can't be right surely? I did ask once and was told 'It's complicated.' - as this thread bears out.
That was the case up until 1976 as I recall. When the pay banding changed about then, it helped neutralised the pay loss for SNCO's joining the Regiment, by augmenting the differential in loss with 'skills' pay. SF moved into a higher band.
