But they still need to find a WWII military expert, and Dale Dye isn't it!
, Dale Dye might get a few of the details wrong, like the hand signals. But with his help, they did manage to make some extraordinarily realistic war films, such as Saving Private Ryan, Platoon, and others. He puts the actors through a real boot camp where they at least spend a few weeks learning what an infantryman must endure, and I think it helps in the final result.
Unfortunately, the Greatest Generation of WWII veterans is fast dying out. Both my grandfathers fought in that war, and they are gone. Those that are left are aproaching their 90s now - those that were raw recruits. Practically none who were senior officers or instructors are left.
The only thing you should feel when shooting a terrorist: Recoil.
