Some problems include leaning to the right while crouching hides your body. Aiming downwards from a ledge or something is not advised unless your leaning.
All those 3rd person view mods out there have a problem, the head of the ghost is in the way of your view and you can't see what your shooting. I changed the files up a bit and moved the camera so that its more over the shoulder and you can now see your target area more clearly.
the original files can be found here: Ghostrecon.net
I only edited some coding.
To install, place the 3 files into another file called anything u want. then take the file that you just created and place that into "Ghost Recon Advanced Warfighter\Local\"
If you do not have a "Local" folder, just create it.
Then go to the "Ghost Recon Advanced Warfighter" folder and find "context.xml". Open this in Notepad. Change the part that says something like "language = " to "language =<(name you called folder)>
Run game and play.
If you have any problems, feel free to comment.
