Germany had MINI NUKES in 1945.

[=D.C.L.I=TuRb0jUg3nD]

the water plant was repaired, but shut down soon after. The remaining heavy water was to be sent to Germany, but the same commando team + reinforcements (if I remember rightly) planted and detonated a bomb aboard the ferry bringing it to shore across the lake from the factory. The norwegian commandos lived all winter in a small hut on the Telemark mountain plateu, and famously had to resort to eating moss when the going got real tough. All very exiting! (TTR map idea, anyone?)
