(Firstly I have searched for help on this on the xbox.com forums and had no success, mind you, the forums have been changed for the worse)
Anyway, I am doing the Khe Sanh level on Veteran and i am struggling on the section to head down the hill (with the barrels). I have been on it for 6 months (i dont play solo often) and cannot pass it. Im very frustrated with it because it just seems impossible. Any help is very much appreciated. The furthest I have made it, is to the barrels and thats it.
