It makes no sense to me that in a country where military orders require the royal family's decision/consent, no one thought that sheltering the princess and not teaching her about military affairs was a very, very bad idea. I'd get it if she was just a puppet or a mascot, but she wields total power over the military. What is wrong with these people. No wonder they are losing this war so badly.

And why didn't the enemy mechs ask for the cornered APC and kingdom mecha to surrender? Executing them like that is kinda inhumane. If that is the standard morality throughout the Empire, that must be a really shitty place to live in.
