yeah? prove that! mostly all testszenarios the IS or rifle will win.
Have you seen what a rifle grenade does to Riflemen or Infantry Sections? Have you seen what an MG42 equipped Gren sqaud or two behind some simple sandbags can do to 3 or 4 Riflemen or Infantry Sections when they try to close in to attack or capture a point? This isn't necessarily bad or unbalanced in and of itself until you consider how friggen expensive the Allied units and their upgrades are to keep them even just on par with this 240 manpower unit (thats only 40 more MP than a sorry Rear Echeleon sqaud) and basically free access to upgrades and abilities.
