Further to my ‘Royal Air Farce’ comment the statement below now appears on forces.net:
The Royal Air Force is promoting the use of gender-neutral pronouns to encourage inclusion and diversity across the service.
Alternative pronouns to 'he', 'she', 'him' and 'her' include 'Ze', 'Per' and 'Hir'.
The language system will be launched within the service rank and title protocol, which could have previously seen female officers referred to as 'Sir'.
Under the new environment, a Leading Aircraftman could be referred to as a Leading Aircraft-Per.
