.. and we've yet not even touched on the possibilities of undocumented isolated cases of mercy killings of our own soldiers;
and desperate measures under extreme duress to silence loud hysterical panicking young soldiers...???

..and it's such gaps of hard evidence, allowing room for plausible speculative scenarios that arouse interest from creative artists
fascinated by human nature and psychology under the worst nightmare conditions..
