The GD branch is long dead. These days our Aircrew are divided into Flying Branch and the Non-Commissioned Aircrew (NCA). For the Flying Branch, the ‘Sub-Branch’ are Pilot, WSO and RPAS(P). For the NCA their ‘Main Trade’ is WSOp. Then you get the capability types - Fast Jet (FJ), Multi-Eng (ME), Intelligence Surveillance Reconnaissance (ISR) and Rotary Wing (RW). So a helicopter pilot would be a Pilot(RW).
Also, the disastrous ‘Wg Cdr Any’ policy is also long since dead - oddly enough you need certain suitably qualified and experienced persons (SQEPs) to do a lot of these jobs.
Finally, I have read a lot “best man for the job” - surely this is “best person for the job”? It would be great to see some more female Aircrew in the top jobs.
