Do stop thrusts end movement?

Thing is Newtons Third law in abstract doesn't take into account friction, footing and likely braced weapons. i.e the situation is not just two frictionless objects colliding (but yes it will apply at some point if the forces are great enough to overcome all that, as you say above it how you view knock back that's the key)

Another possibility to consider is center of gravity when it comes to knock back. Hitting the target below the center of gravity or above it will produce different results against the center. Hitting above the center while a target is running full out would be like clothes lining someone. Hitting nearer to the knees would more than likely cause a stumble effect - all without having inflicting ST-2 damage.
