In the latest dev build the animation for walking is broken. Model just keeps repeating the first step of the STRAIGHT movement, walking sideways or transverse are not affected.
I made a .gif to show it. You can see the best result near the end when an other soldier is running in front of me
I've noticed that it seems like the animation is attempting to rapidly switch between the two walking-weapon-lowered animations, with one arm swung freely, and the other with both hands on the weapon. Walking at an angle works just fine, only seems to occur walking forwards.

Also, other clients can see your animation just fine and you can see them just fine aswell.
It's only broken locally
