Ok-I am new here but I've been building WWII tanks since the mid 70's-here's a website that offers lot's of streamed WWII videos-you can sign up for a free trial or get a subscription and watch the stuff over and over again. Check here http://www.reeltime.com/TitleDetails.aspx?mediaID=1293
I was just watching The Great tank battles of WWII and it is a great resource for diorama ideas. I would have love to have this stuff available when I was starting out building.
