TOFO, Despite my age I am not that far out of touch having only retired 5 years ago.
TS, I can't disagree, certainly FS and MACR can certainly do the roles, but not all.
My last FS was very professional but lacking in other ways. His predecessor should have been an officer but was happy where he was and didn't want a warrant.
Now a previous FS, also TG9, was brilliant as a Sim Controller but I don't think he would have been happy with a commission.
I guess the bottom line is do those NCA, suitable for a commission, actually want a commission? Even if commissioned, or not, could they be retrained in a wholly different role?
