... this one has several things going on. Many of them have been detailed in these reviews, but while the technicals are important, the message is too.
The message here is the human cost of combat. What it costs to be a warrior. What they have to live with after the firefight, the battle, the war, is over. Those that have never been in a war, never seen a close brother-in-arms killed or watched one reduced to an incoherent, broken human in the fetal position that just hours ago was a fearless fighter, have no idea what war costs. How it feels to realize you've killed a human. How it feels to see a human killed. You know yourself and everyone else much better after days and weeks and months of killing and dying day and night; it grinds everyone down to who they really are. You realize things about yourself you didn't know, and if you survive, you have to live with what you've done, or didn't do. It finds the bravest, the weakest, the foolish, the most determined, the coolest under fire, the cowards, then exposes them. That's what this film is about. The brotherhood of those that have been in the fire and tempered by it, the loss of those same brothers, those that failed in the crucible of combat and how profoundly a warrior understands the price of war.
