“You go to war with the army you have, not the army you might want … ” – Donald Rumsfeld
This is the rare time where I disagree with a quote. As a leader, you can delegate authority but not responsibility. A leader is responsible for his or her subordinates’ actions.
At the start of World War II, the German army pushed decision making down the ranks as far as possible. Commonality in training and understanding their commanders’ intent made this possible. You don’t go to war with the army that you want, you go to war with the army that you train.
