Assuming things should be reasonably similar, the imperial land tank (the one that "rockets" is hiding in). I'm assuming by how big it is that'd it have some kinda crazy main gun and a whole lot of secondary weapons. Pretty sure it could splatter a spider tank anyway. And then 100 Spartan II s. Given that they can punch a wraith to death and spider tanks seem less armored, I'd be a massacre. As for the captains, they'd have to stay spread out to keep from being land tank fodder. That makes them easy prey for Spartan IIs. They probably wouldn't even need guns. Lol
