The question came up at the range I RSO at , so I pose it here for an informed answer bereft of marketing speak or Cleetii chest pounding.
What is the actual , real world purpose for these types of weapons? Shooting Soviet troops in the Fulda Gap? Low recoil SMG ? Primary for support troops that's superior to handguns ? Bragging rights toy for Rainbow Six & Stargate cosplayers?
Ancillary: does the primary purpose of these arms have any relevance beyond "just because" for civilian use given commercially available, easily purchased ammunition?
