Franz Josef's Army

[Greyfox]

Chaco War: The Bolivian army was organized along [then] modern lines. A binary regiment, with battalions of 3 companies, of 3 platoons, of 2 squads, each with 2 LMGs. Their heavy weapon support is rather clumsy, initially having field cannons.
The Paraguayans start with a more primitive organization, much like earlier WW1. Their regiments are triangular, with battalions of 3 companies, of 9 sections, each with an LMG. They are trained better for infiltration and independent action on the section level, much as the late WW1 Germans. Later they switch to a triangular organization, all the way down.

You have a good book suggestion for the Chaco war?
