So, I have a triple monitor setup, and The Original weapon for Soldier has an animation bug when viewing in ultrawide... His left arm is frozen on the left side of the screen.

So I decided to fix the animations myself.

The left arm is completely unused in the official animations, so I just moved it behind the camera... In other words, the animations should appear completely unchanged for those using a single 16:9 monitor, but should be fixed for those using an triple monitor ultrawide setup like me.
