Platoon is a 1986 war film written and directed by Oliver Stone and starring Charlie Sheen, Tom Berenger, Willem Dafoe, Forest Whitaker, Kevin Dillon, Keith David, John C. McGinley, and Johnny Depp. It is the first of Stone's Vietnam War trilogy, followed by Born on the Fourth of July (1989) and Heaven & Earth (1993).

The story is drawn from Stone's experiences as a U.S. Infantryman in Vietnam and was written by him upon his return as a counter to the vision of the war portrayed in John Wayne's The Green Berets. The film won the Academy Award for Best Picture of 1986. In 2007, the American Film Institute placed Platoon at #86 in their "100 Years...100 Movies" poll. British television channel Channel 4 voted Platoon as the 6th greatest war film ever made, behind Full Metal Jacket and ahead of A Bridge Too Far.
