I've always wondered, were Dare to Die troops real, or just a gaming conceit?
In the Documantry film "Modern Warfare in China 1924-1925" is a short scene showing a unit of soldiers only armed with large swords very similar to those miniatures.
They are called "detachments of special destination" there.
So the question is, what was their "destination"?

I think, they where not assault or fighting troops but rather responsible for beheading of "special" prisoners after the battle.
