I've read posts of people (including me) wondering why their camera is fixed (no free roam) and how they can fix it. All you need to do un-check the box that says "Battle Realism" under "Options" and then "Game Settings" then you will find "battle realism".... uncheck that then you are done.

P.S: to the gods and godesses who already knew this (and others secrets of the universe) who will start bashing the post, this post isn't for you. This post is for those who didn't know.
