Steve;
You should be able to do a simple Google search and come up with all sorts of reference photos.
I typed "NORMANDY" "KNOCKED OUT" into the IMAGES search and came up with quite a few pictures of all kinds of vehicles from Tanks to Autos.
See what you get with
"CAEN" "KNOCKED OUT"
"FALAISE" "DESTROYED"
or some similar simple searches.
Cheers;
Gregory
