Are all the documentaries of World War II filmed live? Were there cameras at that time? Do they have to take the cameraman with them when they fight?

There are war reporters. On the front line, hand-held cameras are generally light, and color films have also appeared, but they are quite rare.

So many historical shots are actually taken. Of course, some photos and films are posed according to the needs of publicity. We also posed a lot in self-defense against Vietnam.
