Random Worldbuilding Questions (Biology, Geography, Society, etc.)

I am working on a campaign that deals with large scale armies fighting each other for control of a continent.

Where can I learn about war related things like this?

Battle formations, psychological aspects, logistics of running a large army, training, war eddiquite, etc.

It's overpriced new, but the used price is pretty reasonable. I own it, and it's a very good book if you want an overview of defense heavy industrial warfare. It covers every single point you raised to come degree, but it focuses mainly on the experiences of the individual soldier and civilian, so you will find little in the way of grand strategy, biographies of major figures, or historical timelines.
