Economies of scale occur in warfare just as in commerce. It's easier to provide a monolithic vertically integrated supply chain than it is to provide equivalent support to hundreds of smaller units. There's also the psychological impact of facing superior numbers. Any sort of operation, whether it's rapid-fire skirmishes or long-term sieges can be better performed by the army with bigger numbers, assuming commanders of equal knowledge and skill.

It's also a hell of a lot easier to disrupt said monolithic support structure. Army travels on it's belly.
