TBH in the RAF the only true promotion for our cadre is Flt Lt to Sqn Ldr. It is not competitive promotion before that so does not really factor. After Sqn Ldr it is simply who can kiss it more, and for each rank after it is who can forget where they originated from first and can try to re-invent the wheel !
In our air force these promotion's would not be recognised or attended because most could identify immediately the majority are service writing knob's rather than the 'good stick' that isn't a mess sec !
