I always did like the Gurkhas...

Just picture the scene as a soldier returns from hunting an arch-enemy. Commanding officer: 'Did you get him?' Soldier: 'Yes, sir.' Commanding officer: 'Are you sure?' Soldier: 'Yes, sir.' Soldier reaches into rucksack and places severed head on table.

Apparently the powers-that-be were less than pleased with his actions.  No doubt a digital camera could have provided ample evidence of the target's demise, but where's the fun in that?
