First of all: I know that making new content for a videogame is not easy, so I'm not really demanding any of this, just wondering if it'll be possible.

I know that this game has all of the main guns used during WWII, but it would be cool if misc weapons were added to the game. Like the STG-44 "Vampir", that one would be the ultimate anti-infantry gun for the germans. Or even the Vampir version of the MG-42. Also the STG-44 with bent barrel.
And other guns like rifle grenades... the m18 recoiless rifle, mines that can be placed by pioneers... demolition charges (not satchels), the boys anti-tank rifle, the nebelwerfer, or artillery pieces like the 10.5 cm leFH 18/40.

Once again; just wondering if it's possible, not demanding.
