What about Grace? In MF last episode, she literally mind controlled the entire Vajra Hive, I don't know whether her collective consciousness also in command of Galaxy armed forces or not.
PS: During the entire MF series, we only see three people from Galaxy (Grace, SHeryl and Brera), so we don't know whether the fodder FV-27 are controlled by A.I. or by human, or probably the entire Galaxy army is a implant-controlled human...
