My issue is more with hollywood liberties than problems with time lines.
Some examples:
- Shooting the kid
- The Butcher
- Biggies Death
- The 2100 yard shot
Btu like i said, it was a good movie, well acted, well shot.
1) Shooting the kid, I don't recall him saying that in the book so yes all hollyweird
2) The Butcher, seems like a combination of people from raids he was involved in
3) The person who Biggles is based on did die, but it was later after Kyle had retired
4) Not sure on the distance, but he may have made a 2100 yard shot, but it wasn't under the circumstances depicted in the movie.
The movie had 2 sides the war side then the effect on his personal life, thought it was good.
