"Commander, we spot enemy forces approaching the frontline outposts at 3780, 3782, 3340, 0451." The electronic map displayed four lights rapidly closing in on the Red Army's outposts.
"What color?"
"White Army."
"Aha, it's Wind Thunder after all — try to hack the communication response at the 3870 coordinates."

In this confrontation, there were four different colors representing four major academies. The Royal Military Academy of Yingland was the top-ranking for many years, hence, deservedly the Red Army. The Golden Sword Academy was blue, Wind Thunder was white, and St. Calina was yellow.
