Just letting you know I appreciate the effort you're putting into this. Nothing I've read has overly contradicted my understanding of war throughout history, and I do a lot of reading on it in my spare time too! I'll definitely point out anything I can clarify. Perhaps a large section of mercenary forces and their use throughout the years (As opposed to the relatively 'new' professional armies) would make a good addition? Their use certainly had a huge impact throughout history, including being one of the main reasons (In my amateur historian opinion) for the fall of the Byzantine Empire. Definitely looking forward to more updates when you get to them! Also, repeatedly mentioning Zizka gets you major points, my personal favorite military commander.
