Yups, the RGUN did fire at the random ships (maybe due to arcs being able to target certain ships only, I can't tell right now as I don't have java installed on this pc), the LFRG never moved into range as I did intend for it to do, it just turned away to head towards the other ships. I reckon it was the combination of using the Attack command with the priority targets that caused the behavior, so perhaps next time I'll end up having to use a more direct set of commands or perhaps Patrol or microjump them. Overall, the CRRCK is a nice vessel - pretty decently armed for its price, reasonable speed as well. It does lack some more point-blank firepower though. Unfortunately, the RGUN was too slow (in my opinion) to be a good escort for it, if you rely on jumping it regularly.
