To Blaster- I guess I should have clarified better, sorry. Considering the German's overall thicker armor, a number of the smaller caliber rounds wouldn't penetrate the armor. Yet at the same time the concussion would knock the paint off of the wall on the opposite side of the impact, creating a form of shrapnel.
To Owen- That's interesting. I've never heard that before. Would they do their whole compartment or just specific areas that the sun tended to hit?
Thanks guys!
