Hello. I have a problem with my formation in Array.

I have three red Heroes: Leonidas I, Lancelot and Geraint

and I have seventeen orange heroes: La Hire, Sulla, Desiderius, Seleucus I, Sobekneferu, Boudica, Scipio Africanus, Brutus, Fulvia, Artaxerxes, Clovis I, Shajar al-Dur, Hamilcar Barca, Hypatia, Demophilus, Cassander and Antigonus I

Which heroes and where I should set in my formation in the Array?

Thanks for Your help .
