First I just want to say that I love the hard work that went into this mod and I respect the creator for his work.
But there are a few major issues with the single-player that make it very unfun to play
1. The high enemy count, you are given a squad or two of a few guys, then you have to fight against a very very high enemy count in the missions, or in Cliffhanger where it's two guys versus an entire army, the mod creator should lower the enemy count, or at least give us reinforcements, the "one man army" kind of play style works in Call of Duty, but not in MoWAS2.
2. Having to protect main characters in a few missions.
3. Tanks being vulnerable to molotovs, these are modern tanks and they should be immune to molotovs.

I tried the MW2 singleplayer, and I was instantly turned off by all of these issues and left the mod, I hope the creator sees this and does something to help, I was playing it on Easy too
