It's true, you have to be very manly to be constantly pissed or on holiday as most of the guys in the forces who I know seem to be.
however many soldiers are idiots who couldn't do anything else in life.
Some fantastic sweeping statements there. Do you want to brand all priests as sexual deviants and truck drivers as murderers as well?
Some people are idiots – the statistics are probably the same in any line of work. Most of the forces types I know work pretty hard and a few of them work exceptionally hard, repeatedly deployed etc. Some are twonks – but so are some people who never wear a uniform.
