This whole "class" thing has always bothered me.
Useless shiny-arse polyester uniforms that happen to have had a commission routinely trot out the "should have tried harder at school" nonsense.
Not everybody has the interest or ability to command. However, there are some awfully thick people in positions of command in the Services, and some awfully bright people in the "lower ranks". Granted, neither are universal.
However, to be looked down on by those that have held the Queen's Commission doesn't do that office any favours at all. Fortunately, this thread is a good indicator that times are changing.
