If Captain Amanda's responsibility was mainly to oversee the military operation and battlefield strategy, Lieutenant Charlie Field's responsibility was in the political framework and interdivisional relations.
Speaking of which, the federal political system was rather special. The military held the most power, and the Council of the Seven Stars Generals was the highest political echelon. The seven generals governed the city-states under their jurisdiction.
The federation had a symbolic president, who was selected from among the Seven Stars Generals in turn. The Seven Stars Generals mainly belong to three major parties: the Socialist Party, the Republican Party, and the Democratic Party, thus making these three parties become the three major ruling parties in every election where they would take a turn as the winner.
