Jagdpanther and Jagdpanzer IV had both just 1 mg in the hull
The early versions of JP IV had left and right one cupola with each one mg behind.
The late version only had one.
thats basically what i said - this version has the long 75mm gun which appeared in later versions. so there is only 1 mg.
i dont see how the jagdpanther will be that much better than a standard panther right now. sure, it has the best gun of ww2 with the long 88mm, but this only makes a difference if there are churchills on the map, because shermans are 1shotted by both guns anyway.
the only advantage the jagdpanther has over the panther ingame i could think of is the lower silhouette, but i would rather like to have a turret and a coax gun. so i dont expect much of it, its just cooler and has more style, the advantages it had in reality cant be included in a game.
