Which war film was most emotionally touching: Black Hawk Down, Platoon, or Saving Private Ryan?

I saw some of Black Hawk Down, never saw Saving Private Ryan, but I did see all of Platoon which was clearly one of the saddest films I've ever seen. I just really felt bad for everyone in the film: the soliders and the villagers. I could feel deep pain when the U.S. Army torched the Vietnamese village and when they killed some of the people all because of fear, anger, and desperation. They got used to murder. I really felt bad for Elias as he was the only one (and later Chris Taylor) who cared one bit about the natives and didn't ume them as helping the Viet Cong Army they were fighting against in an effort to destroy communist influence. I don't remember why there was protest against the war but I think it had more to do with the fact that Vietnam didn't attack any U.S. territories than the fact that U.S. soldiers were dying because when World War II broke out the U.S. was eager to get revenge on Japan for attacking the Pearl Harbor military base.
