Well, yeah. But a mortal without control to the armor is just a log. I mean, it could be a way to incapacitate some of the troops, but even then, it would just send Xerxes from "Screwed in 5 minutes" to "Screwed in 7 minutes".

From what I understood though. Lif and Termy are the ones who know it. I just don't see the point in discussing this too much anyway, Amestris is bound to lose.

Fair enough. 

Xerxes is doomed to lose, yeah, but Poog has made it clear that Lifprasil fully intends upon uniting Galbar under Alefpira, one way or another. Those who won't join willingly be made to.
