I liked Billy in that battle. Human projectile!
And I think the coolest "character" in my battle was the UCD transport. That thing one-shotted two vehicles, both of them with more armament and HP than it had, with gargantuan damage rolls. And if the Assyrian mecha is a character, why can't it be one too? Rudolph was pathetic. He got off one missed shot and then was gunned down.
