Which means in any war the majority of the people in the service will never see combat. So they will never see body parts.
And they get left out of the movie. Yet without them doing their job the guys on the front line would be reduced to using rocks. Which are very versatile, you can throw them and boil them for soup.
So a realistic war movie will never be made. The closest you can get is to read the letters and journals of those who were there. And skim over the dull bits. :)
C’mon now, next you’re going to tell us that the majority of the C4 plastic explosives issued to Vietnam combat troops was used to blow foxholes, blow up trees for fields of fire clearance and to ‘gasp’ cook our C-rations. :o)
