"We need him to slow down as much as possible. This position will force him to curve north of the edge of the asteroid belt. We want him to be facing at an angle to his approach path when he gets close enough to open fire. He will expect a trap, so we’ll have to bury the welcoming committee deep to shield them from a random scan. And I’ll have to launch them very late, after he’s committed. He’ll probably get a chance to fire on me before they get to him. So I need to have something that can hold off some missiles."
