Deathwatch

Factual error: The rifles the British soldiers carried in the film were Lee Enfield rifle No. 4's, these did not go into production until WW2. They should have been using an earlier version of the Lee Enfield rifle.

Factual error: There is, and never has been, for that matter, a Private First Class rank in the British army.
