If we're making odd analogies to politics I think most high performing teams tend to end up in the Marxist "From each according to his ability, to each according to his needs". Or instead of the military, think of a basketball team. How do five excellent athletes work together. The coach is not a "dictator", nor is anyone on the team, but they also don't vote on plays. They know what each other is good at and, based on the situation given to them, execute in a way that is most likely to succeed.
