Well as you are kind of lost in space.. searching for your battlestar... you need money + equipment for survival.
So mining and/or trading with fighter escort would fit for me.
I do see BSG miners around now and then.. but mostly they are alone.
about Outcasts:
I thought that the IMG are hostile to Outcasts mostly because they tax/pirate their traders and mining operations. So the IMG defend them. Ok you may choose not to stick to that roleplay.
As it is now the BSG is attacking Alpha at least once a day....which is way more often than Corsairs... kind of strange for me.
What does the BSG try to achieve with that? The only thing you can achieve in RP sense is a destruction of some Outcasts ships.
If you want to keep doing it (you can).. then I also suggest either generic Military ID or BHG ID. Acting as "defensive division of IMG"
Being friendly to Corsairs (and coordinating attacks with them) seems very strange to me as well. I would say IMG is at least unfriendly to Corsairs. - Looking at Omega 7. Even if you don't roleplay IMG... you should still know that Corsairs will just attack and overrun you once the Outcasts get weak.
