In a year full of pale sequels, I'm pleased to say this one's very good. I played through the single-player story on wimpy mode. The dialog is predictably "gritty," and it includes the usual storyline of the maverick soldier who refuses to leave his men behind .. but once you relax into the cheesemo, predictable "war hero" stuff, it's kinda boy-game fun.
The other interesting thing about the multiplayer mode is that the choice of "careers" for your character doesn't seem to actually include a "heavy grunt" sort of character. Everyone is specialized for something: heals, turrets, sniping, stealth &c. The talent trees for each are quite short and narrow, and different maps are better for different careers. It makes you try more than one career, and switch them up to match the map and your teammates' styles. Well done!
