Yeah, Blauk is right.
I overlooked the three night bombing raids of Helsinki.
But there wasn't any regular use of B-25s on Finnish front, like the A-20 was used for example. And that plane was mainly used as torpedo bomber/photo recon plane. B-25 could very well be used as "a generic soviet bomber" on snapshots/scenarios on the Finnish front. Because of it's slower speed it would suit better than the A-20 on many occasions.
