It is a complete war action violence related movie. No sex or nudity show in this movie. Not even a kiss. A woman hit by a bullet, when she take off her t-shirt, her bra visible.

Lots of shooting, very very little blood shown. this movie could have easily be rated pg-13

Most of the language is within a few minutes H--, etc.

1 use of the f-word as motherfu*ker, which probably accounts for the R-rating.
