I just watched Warfare last night and highly recommend it for anyone that has romantic thoughts of combat. This is not a rah-rah portrait of war. It's written by the former SEAL who was there. He was concussed but kept on going and they relied on the memory of all the other SEAL team members to helped piece it together.
It's directed by the same guy who did Civil War and is actually pretty far removed from that in comparison. The military advisor on that was the same SEAL who wrote Warfare with the help of the director. There's no music soundtrack. In the end, things look rather fruitless considering what they sacrificed but that is basically the cost of war. It should be required viewing for all the gung-ho wannabes out there.
All the best,
