I must say I am very disappointed in the new animation where you walk with your primary lowered and swinging your left hand. It looks extremely unprofessional for a professional fighting force. Not only that, but it looks sloppy and uncomfortable. Lets pretend you're carrying Lynx anti-material sniper rifle. Your right wrist would either break or sprain to the point where you can't even use when its crooked to that angle with no support from the left arm. It looks very unnatural and while using the combat pace your left arm flops around and looks very silly.

tl;dr re-do the walking with gun lowered animation similar to those in ArmA 2.
