Weapon request on the machine gun.

It might be difficult from this close-up, but vehicle request on tank. It should be the Panzerkampfwagen IV, but I don't know enough about it to make a solid determination on it.

I'm gonna go ahead and say confirmed on it being a Panzer IV since the shells say "7,5 cm" and given the turret shape along with the cupola.

I'm going to say that the machine gun is likely an MG-34, which would make sense as the Panzer IV used MG-34's for both it's bow and co-ax mounts.
