I think, just because someone can do something, doesn't mean they should - Adam will have learned a priceless and very bruising lesson about his new role - at least, one which those who follow him won't make. I don't think that having experience in a role makes one automatically better qualified for it. If civpol approaches SNCO/Warrant Officers, as it does, and asks them to join as PC with quick promotion to Sgt/Inspector, I can't see why, in principle, it shouldn't be able to identify a Sqn Ldr and transfer in skills at that level, too. Are crime fighting skills as readily transferable to war fighting? Probably not. That's not to say you shouldn't trash the culture of an organisation by not paying due service to its traditions, culture and values though. Hence my first point.
