Platoon (1986)

Platoon tells the extraordinary journey of Private Chris Taylor (Sheen), a young, naive American who arrives in Vietnam and quickly discovers he must battle the Viet Cong alongside the gnawing fear, physical exhaustion and intense anger growing within him. His two commanding officers (Oscar-nominated Tom Berenger and Willem Dafoe) draw a fine line between the war they wage against the enemy and the one they fight with each other. Meanwhile, the conflict, chaos and hatred permeate Taylor, suffocating his realities and numbing his feelings to man's highest value: life.
