So the question is, why have a rank structure or Officers and SNCOs at all?
I would say the rank structure is more for the likes of WHQ, RHQ, HQAC etc to be able pin things on people.
We struggle for staff full stop. I have to say that going back if the same system was in place now, how many current Officers would bother. I don't know very many that would.
I used to think like that, then I grew up and realised nothing is black and white.
People in general commission with good intent, but then that funny old thing called life rears up and things change. I've known a lot of CWOs who were going to change the world, commissioned then got married, job pressures etc etc and left, leaving the world unchanged, or they just did what they were doing. I've never seen that it mattered wrt time served. Should people resign or made to resign if they don't want to take a command, who knows, would they leave the Corps on the back of it, based on the fact we're overrun with staff and people wanting to join, so we can lose a few. I've known a number who've been forced to take a command are in post for 9-12 months, then go NEP on some pretext, never to be seen again. Prior to the forced command they were good officers doing a decent job. Who loses?
God knows what squadron(s) you've been on but I don't know people like that, it's the urban myth that we all ascribe to.
