In the Aztec army there was a military commander in chief that was the king/ the tlatoani. That person was then assissted by a cihuacoatl. After that, there was four more of the highest ranking nobles. Those nobles were usually related to the king. Those four titles were called huanhuanaco, tlacochcalcatl, tlaccetacatly, and tillancalqui. All of these people were the important leaders that helped rule the army the way it was run.
