CCF
The Combined Cadet Force is an institution favoured in British Grammar schools which prepares students for careers in Her Majesty's Armed Forces.
Better classes of school will have an OTC or Officer Training Corps which pretty much tells you all you need to know.
No matter how professional our forces become, the CCF is always trapped firmly in the era of National service. A weekly stint of drill, polishing a shared Boer war bolt action rifle followed by three hours of mapreading and Morse code.
Inherent in the structure of any school-based, voluntary, paramilitary organisation are the seeds of it's own downfall.
After the compulsory first year, intelligent people leave, disheartened by doing push-ups in puddles and wearing an ugly uniform made out of a kind of fibreglass and horsehair matting. Of course, promotion is dependent on more than a year's service.
...You'll have spotted the problem then...
Within three years, any CCF unit has become a self-fulfilling hotbed of sadistic bullying.
However, the certain knowledge that only the thick get promoted has served many ex-cadets well into later life.
