What FPS game does this screenshot (of a Skorpion SMG) from the Dxtory features page belong to

While looking at the features page for the Dxtory movie capture tool I noticed this image:

It looks like the weapon is labeled "Skorpion" (which is a real weapon) in the lower right along with some other text (though I can't make out the rest of the text).

I tried to do a reverse image search on TinEye but the only other sites which came up in the search were in a foreign language and used the image in the context of the Dxtory tool rather than the game itself.

I would guess this is one of the many Call of Duty games, though I'm not sure which one.
