ELI5: How were recordings taken during WWII?

I've been watching some TV and noticed that a lot of the camera angles are ahead of the moving tanks, even when they are firing, like there are dedicated camera men in battle. Same thing goes with planes. It seems like recording footage would need a dedicated group because you shouldn't be recording mid-battle.

Militaries have members who's duty it is to record and photograph combat and other activities. They are collectively referred to as "Combat Camera."

A lot of the footage you see in documentaries is also staged footage of exercises and demonstrations for propaganda and training films.
