Well, considering that the adventure has to be combat-oriented, I thought about spec-ops team operation (OMSBON NKVD or Razvedupr recon/diversionary team, probably.)
I'm open to players' wishes and suggestions, though.
And while we're at it -- few questions:
a) What style of play? Gritty/realistic, cinematic, something in between?
b) What about fantastic elements, like ones mentioned in GURPS Weird War II? Also, should I stick to the history as we know it or some leeway will be allowed?
c) What period and region should I consider?
