This is an addendum to Spyderkl's blog about giving career advice to Stanley McChrystal, I would like to note that your man in Afghanistan doesn't hold a candle to British World War One hero, Tommy Woodroffe.
The veteran became a broadcaster for BBC radio and was asked to cover the 1937 Royal Naval review. It only happens a few times in a century that the Royal review happens at night as it did in 1937. The ship go out into the Thames with their lights up until, at a pre-determined time, the entire fleet goes dark. Well, Woodroffe had a meal and a few drinkypoos in the hospitality suite of the boat before he went on air live from the HMS Nelson.
This marked the end of his career at the BBC. Both Woodroffe and McChrystal went out, if inadvertently, in style.
