The US military is more a collection of balkanized battle networks that require large quantities of time and human struggle to cohere. And that is the deeper problem with our current military business model: each sensor or shooter that we add to our battle networks to increase their speed and effectiveness requires corresponding additions of exponentially more money and manpower. And sooner or later, we will run out of both, especially in a long-term competition against China, which has four times as many people and could soon have an economy as big as ours.
