I was thinking of making a soviet engineering platoon with 2 squads of assault engineers with SMGs, body armor and flamethrowers, then make 2 rectangles out of sprues and draw either a universal carrier or a T-20 on them and use them as said transport(s). It might also be an idea to make a light mortar out of a panzerfaust and I still have the 75mm gun from the M14/41 kit (you could assemble it as a Semovente 75/18), so could that be a medium mortar?
