I have some early impressions. Playing the Yank in multiplayer, I'm finding the degree of mg42 lethality is pretty high. A typical firefight will start with an opening exchange of fire between enemy squads, with usually pretty low M1 and Tommy lethality, though the BAR can get some hits in. Once the mg42 of the enemy squad is sighted on the Yank squad, the Yanks start dropping pretty fast, and if the squad loses a couple of guys, then low Yank morale may very well kick in, and the other soldiers can crack or lose their combat effectiveness, and so quite rapidly a Yank squad is finished. Even when guys have hit the dirt in ambush mode in a building, they still get chopped up.
In my latest battle, the German player took out maybe half a dozen of my (unsupported - no tanks) squads through mg42 fire alone. He didn't need to fire a single cannon shot.
Any thoughts from other players here? I have seen the above sequence of events a good dozen times now in multiplayer play.
My standard of reference here would be the Gold Juno Sword mod, which I consider to be one of the best CC5 games. I think there the mg42 had less lethality, and so the German gunner would have to spend more bullets to hit a target, which would make the German player think twice about burning through his ammunition.
