The canon in sevestapol isn't really useless IMO, I usually use it to blow up the heavy artillery that comes in later in the mission.
Also, Arsenal (The fucking Allied sneaking mission at the beginning of the campaign) is very... very... very... frustrating... especially in co-op where you can't just save every 5 seconds and reload if something goes wrong. EDIT 2: Also, when the alarm is raised, a bunch of halftracks and armored cars filled with infantry come from off map... lots of them...
There's an insane playthrough where these two guys completely own that level, I might go search for it and see if it will help anybody here.
On a lighter note, luls during a co-op of that mission.
LinkyBy the way, for anybody who thinks the voice acting in this game is bad, you should see the voice acting in the game that came before this, Faces of War. Oh jees. They actually put effort into this compared to that game.
EDIT: By the way, one thing I find somewhat useful, is any time you have to move your men a somewhat good distance, hit the numpad plus button as they start moving and they'll reload as they move, then when they get to their destination they will have fresh magazines.
EDIT 3: This isn't the video I'm looking for, but
have it anyways. I don't know how you'd manage to pull this off with fog of war enabled.
