The Bell P39 Airacobra for the soviets - 5 out of 10 highest scoring soviet fighter aces flew this machine.

Don't understimate +3 initiative. I have a pioneer with move +1 and initiative +3 - i can attack infantry in the city without softening it and only have usually betwwen 0-1 loses.

But the best movie with Nazi zombies is Dead Snow.

Not finished with DLC'42
It hasn't the most kills, but i'm sure it will change sooner or later
Wurfrahmen 40 1298 kills - two time a hero with range +1
With the 4 hexes range it's my best ary and flak killer.

Nazi Vampires woulb be also a nice scenario, in this movie they even found a way to survive in the sunlight.
