Mmmmm. I think there is a Gurkha who has won it twice.I'll check.

Norsk Hydro's Heavy Water Plant at Vemork in Rjukan was destroyed by Norwegian saboteurs in February 1943. This sabotage was widely known about in Norway as well as abroad.
Operation Freshman
The battle to prevent heavy water production is the most dramatic chapter in Norwegian war history. For this was a fight against something bigger and more threatening then ever before; against something which was able to rock the very core of our universe. The atom bomb in the hands of the German's could have turned the course of the war in Hitler's favour, and history might have taken a completely different path. The despot could have become the master of the world. However, this new weapon was not completed before the Nazis were defeated, and we owe great thanks to those men who risked their lives to carry out sabotage missions which were more daring and audacious than anything ever undertaken before.
