I doubt the chain of command will care if they get 1 or 2 letters from a few DE officers as I suppose they will write this off as some misled officers being idealists or that they were misguided by their SNCOs, equally 1 or 2 gapped SO1 or SO2 posts won't effect the manning of a front line squadron.
For any CO, their influence is only temporal, but their reputation is eternal. Whether they are derided or celebrated is in our hands, and we must all make them realise that this is the issue on which they will be judged.
Whilst I agree with the sentiment of this rallying cry, 20 or 30 extra aircrew leaving a year can be easily absorbed by the Middle Wallop production line, long term your naive if you think anything will change because of a few disgruntled voices!
Do you think the chain of command cares about the noise of hooves?
