Issues with tanks

Both tanks textures seem low res (LODGroup is World)
Sherman tank cannot move and the treads behave oddly in third person
Sherman tank constantly makes the "stuck" noise even when still
Firing Sherman Gun causes it to slide backwards
Sherman Commander sticks out when in open hatch view
Sherman Engine sounds are overwhelmingly loud
Sherman seems to be lacking an idle engine sound
Spare Road Wheels on rear of Stug float in the air off the rear deck of the tank
Stug commander can look only a few degrees to the left, but can almost turn a full 360 to the right
Physical Material Setting for Tank Material is empty and default (should be set to Armor)
