One of the reasons some walls need fewer supports or can get by with less thick materials that I don't think I have ever heard mentioned before is the distance of space a customer can use to swing or run at a wall to break it.
Reduce the "run-up", reduce the power of an impact.
If there is a portion of a wall that people will be impacting , usually from an adjoining tremendous scare, 2 by 4's with a 3/4 thick plywood wall, maybe even bolted together is what may be needed.
