I voted We Were Soldiers, but I think Hamburger Hill takes Platoon about 3 steps further into the reality of war. Having said that, I've never been in war. However, my 10 years in the military, and conversations I've with my dad who was in Korea and Vietnam, leads me to these decisions. I also think that Saving Private Ryan, does a a good job of taking the audience through the personal struggles of soldiers at war. You do what you're supposed to do because you believe there is a bigger reason that makes your situation necessary.
