Now this is more of a Age of War era development while regular autocannons were in development as a stop gap until RAC's start becoming available. these still suffer per shot from the -3 damage vs BAR8-10 Armor types but you have upto six chances to hit them with these. After all stop gaps are fine as long a they eventually go extinct. Showing signs of decline in usage after the RAC is introduced.
