The empire has an armada the likes of which this planet has never seen. Ships ranging from 2 to 20km in length. Tens of thousands of ships. Hundreds of thousands of fighters.
Even for our rebellion it's almost too much. They ever bring their full force to bear we wouldn't survive it. So we have to rely on hit and run tactics.
But I think we can do it. I've trained rebels before, in another war, before the empire, when the Republic still existed.
