I doubt that handful of brigades can make a difference. There are hundreds of 1-4 star generals, but less than a dozen active force divisions.

Sure, every army is a bureaucracy first, and Niiskanen's bureaucrat model isn't far off. Nevertheless, 60+ year old lessons should have an impact on an organisation.

This is particularly frustrating to me because the Heer 2011 structure is almost as stupid (and in part more confusing) than the previous German army structure.
Nobody seems to take "battle" (as opposed to small unit skirmishes being called "battles") serious as an influence on army structure design any more these days.
