Nothing to contribute, unfortunately, but I'd like to say that this is among the most informative articles on this site.

10/10, keep up the good work!

If I could make some requests for some further expansions:

*Early grenades. 

*How to supply train across the ages (and how to fuck up the other guys supply train)

*Moar stuff on 'cowboy' fighting. How did shootouts in the actual Wild West work? (Aside from the Mexican Stand-offs) How did Native Americans raid n' stuff?
