Arma like camera movement!

I've been searching for a while, A basic third person camera movement like arma II has. Where the player is always looking at the crosair and movement solid forward. So not like most Third person cameras where the player can stil go left and right not facing forward. I hope you understand my intentions!

So basicly:

• I want my player model facing forward. (But ofcourse if i turn left and right with my mouse the player turns with it.

• The "Gun object" Is always aiming at the corsair.

If anyone knows any good tutorials on this or documentations i would apreciate it!

Also, I just want to know what you think of the Player Model. Cant resist asking!
