Some points:
1. This is a Military procedure carried out at Military Airfields.
2. Most if not all such Military Airfields have an ATC Service, an ATZ and thus a known traffic environment.
In the civil world, unless there is controlled airspace, it can not be taken as a known traffic environment.
Perhaps, pilots operating at uncontrolled airfields should voice their objections (if they have any) on the R/T when they hear the call "run and break".
