I wasn't expecting soon to be quite so, well, soon.
AATs don't normally have shields. Is this one modified or something? You say hasn't raised it's shields yet, but I keep thinking of Red Dwarf.
"One, we don't have any defensive shields; and two, we don't have any defensive shields. Now, I realize that, technically speaking, that's only one flaw, but I thought it was such a big one, it was worth mentioning twice."
