Remember this is a TV
SHOW. It is edited for mass audience consumption. The presence of cine verite and cameras causes people to act differently. This, I submit, is in contrast to WW2 film where they probably didn't expect to feature in a mass media programme.
Contrast this show with a properly run piece of MOD progaganda, oops I meant properly edited documentary, where you have senior officers taking the place of junior officers.
