The new Salvaged Astromech states that you can acquire target locks and attack friendly ships.
What scummy tactics can be done with this?
I can think of one: Send a Dead Man Switch Z-95 on a Kamikaze run, but this would be an expensive 14 point - 1 splash damage missile and hard to trigger at the exact moment. It will be more effective to use harpoons or assault missiles.
So, what is the purpose of this droid?
