As you can see, the gunboat's presence in Omega-3 was requested

edit--and just to be clear, I shot down the Red Hessian bomber, and then joined against the indy pirate gunboat after he started shooting at me. The ID allows engaging ships that are hostile to Rheinland wherever they are encountered, so that covers the RH engagement. I am also allowed to defend myself, which covers the gunboat engagement.
