Outstanding display Erwin! 
These men in the Shermans were routinely up against superior tanks that were capable of destroying a Sherman @ 1000meters or more. What makes these guys such heroes is that they kept on fighting regardless of this, and would get back into a second, third, fourth and sometimes 5th Sherman and continue to fight on. My Uncle "Rusty" Wells was a Sgt. in the 691rst Tank Destroyer Battalion, part of the Third Army. He won a bronze star in France, 1944 , after he crawled across a battlefied under enemy fire to rescue another soldier.There were many others who deserved medals for being part of tank crew that didn't get the recognition they deserved.
You are probably already aware of the Tanker interviews on CD, but if not I would recommend them highly!
