Question: Would a sergeant-major participate in a mission?
Question: The early versions of the M16 had severe problems with jamming. There may have been several causes; instructions issued that the rifle was "self-cleaning", improper ammunition design, improper magazine design (therefore in a later stage 18 rounds instead of 20 were used in the mag). It is not necessarily a mistake, certainly not by the filmmaker, but there are several writers mentioning serious casualties amongst fighting troops specifically because of jamming M16 rifles. Why does this book/film not even include a hint of that problem which surely must have existed at that time and place?
Question: What does the term "Fire in the hole" mean? It is used in this and many other military films.
Question: An entry on the wearing of full combat gear and arms on the transport to 'Nam has been corrected, reason being that this is done today. This is correct, as rapid deployment in zones with little or nonexistent local military infrastructure exists requires every soldier to be operational when hitting ground. But was this the case at the time in Vietnam? Sure, this is early in the war, before a full scale upbuild but were incoming troops really transported this way, even in '65?
Question: The request "Fire for effect." is used in this and many other war films when calling in artillery support. What is the meaning of this term?
Question: One of the deleted scenes has a young soldier relating a story about one of his tough old SNCOs who was terrified of Plumley. This tough old Sergeant arrives on parade naked except for two Medals of Honor. Is this possible? As far as I can work out the last dual recipients were during WW1 - posthumously.
