How do I make an actor push another actor out of the way while moving?

Whenever I move a group of actors to a location that requires passing through another group of actors they all get stuck on each other. I know there is way to alter the AI navigation to avoid other actors (Detour Crowd with RVO) but I am working on a real time war sim and so I still want actors to have the ability to push off each other when they get congested. I tried doing AppyForce on the Hit event but to do so I had to enable Simulate Physics which resulted in the Actors not moving when a MoveTo is executed and they just fall over.
