To OP, as proof:
Stared who has come to be known as the international bad ***, and the iconic drill-instructor: R. Lee Ermey, or Ermy, or however you fcking spell it.
Then they made an HBO mini-series based off of it.
If you get it in your thick little skull that maybe, somehow, they made a movie based off the HBO mini-series... the movie was filmed in 1987, or '88. Somewhere in that time period.
And it is, by far, the most iconic war movie. I'd even go as far as saying one of the first which all war movies follow now a days. It's between that and Platoon. Which is another really good movie.
