Not sure how accurate it is or credible it is. That looked like a B-17, could have been a Henkel, in a couple images when they were talking about the German and British air forces, although another image did look like a British Lancaster, a modern warship with a Japanese flag was shown when they talked about Japan, the low countries (Belgium and Netherlands) were conquered BEFORE France but that's not the impression you get when you watch it. They skipped the whole German air attacks on British radar stations and airfields at the beginning of the Battle of Britain and went straight to the Blitz, which was not the original plan and occurred later.
Something I was skeptical on was Patton mounting a machine gun in the back of a car. More likely, although I really don't know, was that they had a bunch of soldiers with rifles in the cars on that particular attack.
Disclaimer - I play WW2 strategy games as a hobby, but I'm no historian.
