In general, Bad Moons clan Orks conduct mercantile activities throughout Ork space. But, all Orks conduct many types of mercantile activities. Military supply related activities often get taken care of by meks. Freebooterz seem to dominate most Ork intergalactic trading and related piracy, similar to Imperial rogue traders. Normal planet-side mercantile activities conducted by Imperial civilian merchants don’t have a direct Ork correlation but are usually conducted by Bad Moons or other teef-hording specialists. Mercantile activities sometimes involve kommandos, especially when conducted between orks and other races.
