HELLO
In the game, I see soldier with a skin quite black, or green,
how can I do the same thing?,is there a program or something else for have this kind of skin?

Wtf? Headless players?

There have been some topics by people saying they have seen headless players/asking how to make themselves headless. No, they are not/no you cannot make yourself headless. You can use the Soldat Skin Color Changer and make your heads transparent, which is what the others have done. Your heads being transparent doesn't mean you can't be shot in the head, your head is still there remember.

Quoted from the common question list. For the love of all that is decent, read the stickies from now on. It's not hard, and you'd have your answer faster.
