Actually, the US military is successful more because they prioritize on the spot thinking and only deferring to the chain of command in specific circumstances. As much authority is pushed downwards to the lowest level possible. That’s why the military is so effective tactically, though the high level strategy lately has been rough. The war on terror was overall ineffective, for example, but the troops had a ridiculous k/d ratio. Another part of the success is from training. There aren’t many militaries who train as much as the US military.
