I wrote a bit on it earlier Sentry just a couple of farcical bits 1. Sniping the man in the suit at @ 300yds with a single load of the Bren by the section Sniper from the roof using the normal sights 2. The single post only No.32 scope on the sniper rifle in an earlier scene you glimpse part of the horizontal line remnants through the scope later in the film it is completely gone.
