A former Artist colleague had earlier in his life managed to get himself discharged from an S-type engagement with the Guards (12 months in the ranks for pot Wooperts) by appearing on parade in his slippers. RSM had him doubled off the square and through the paperwork by 10.00.
Another, a serving Artist at the time, was charged with (and subsequently found guilty of) murder. Just a pity he was 2 i/c HQ Sqn at the time, while a third, a humble Lance Jack, only had to get 18 months for GBH to instigate an immediate discharge.
So, parade in unsuitable footwear, bump off your former girlfriend's new lover or smack a chav in the pub - they all are proven to work
