The Boys in Company C (1977)

In the 80's I saw The Boys in Company C,a film from 1977,dir.Sidney J. Furie.
It's a Vietnamfilm.
R.Lee Ermey is in it,as a sergeant.I wonder if Kubrick saw him in it.
It was one of the first Vietnamfilms.

And there are similar scenes to FMJ,like the shaving of the boys heads.The bootcamp.
Never happened to me before,watching a Kubick film thinking I've seen this before(some scenes,they are different films as a whole)

There's also a scene where a soldier,played by a great Stan Shaw,steps on a mine and can't move or he'll die.
Powerful scene,in the rice fields,never forgot it.

That also happened later in the much praised warfilm No Man's Land(2001).Dir. Danis Tanović(Bosnian language).
That scene was what everybody was talking about.

I was just thinking,this has been done before,way before.
