Do you think it would be better to have a democracy during war? (I mean in individual military units, not in a country overall - note that military is controlled by a civilian democratically elected president)

"The enemy's forces are shelling us. Do we want to attack back? Who votes for/against?"

Interestingly I read a history of the French Army mutinies in WWI. One thing that came out of that is lower commanders had a duty to question orders from superiors if they didn't think the goals were achievable. Previously any hint at not following an order was considered "cowardice" and millions of men were led into insane situations with impossible objectives because nobody thought orders from the top could be challenged.

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.
