I'm not sure that COD is "ultra-violent". It is violent of course, but not much more then an average action movie.

Killed guys in COD are just pictures - they have no personality or story. The action is in context of warfare and no one there is believably "good" and "bad". Only better at shooting.
I do not think you can judge violence in such simple way. To use analogy, the movie reservoir dogs has scene with ear cutting where nobody dies. That scene is way more violent and disturbing then dozens of killed enemies by James Bond.
Basically you're pretending to be a terrorist, you have to shoot up an airport full of civilians (who die very realistically, beg for their lives, etc.), and then at the end of the level the main terrorist whose cell you're trying to infiltrate shoots you in the face and you die.
As far as the single-player mode goes, I can't speak from experience... and neither most other CoD players, I wager.
I think that scene is something that makes Call of Duty: Modern Warfare 2 a game for adults, the same way as ear cutting scene in reservoir dogs makes it something for adults.
As far as I know, other call of duty games do not have such scene. I may be wrong on that one through.
