There is a very good reason we were told of the unwritten rule which stated if your helicopter is shot down, fight like hell but if capture is eminent, the last round in your clip is for you.
Not the first that advice has been given for Western troops in Afghanistan.
When you're wounded and left on Afghanistan's plains,
And the women come out to cut up what remains,
Jest roll to your rifle and blow out your brains
An' go to your Gawd like a soldier.
Rudyard Kipling (The Young British Soldier)
