Comanche leadership lesson

I was reading about the Comanche people and these points about their social culture (war leadership) were interesting to me: the emphasis is mine.

Comanche groups did not have a single acknowledged leader.
Instead, a small number of generally recognized leaders acted as counsel and advisors to the group as a whole. These included the "peace chief," the members of the council, and the "war chief."
The peace chief was usually an older individual, who could bring his experience to the task of advising. There was no formal installment to the position, it being one of general consensus. The council made decisions about where the band should hunt, whether they should war against their enemies, and whether to ally themselves with other bands. Any member could speak at council meetings, but the older men usually did most of the talking.
In times of war, the band selected a war chief. To be chosen for this position, a man had to prove he was a brave fighter. He also had to have the respect of all the other warriors in the band. While the band was at war, the war chief was in charge, and all the warriors had to obey him. After the conflict was over, however, the war chief's authority ended.
