So, question, will humans be getting non-"hero" combat castes? I'm just curious, cause from what I read, they used to have an upgrade system for knights of some sort, but it was scrapped because of some issues with it or something; the 5 fighting ones also seem to be more geared for adventure mode or something, rather than fort mode. I'd be happy with just two, since they seem like they might be gimped for nonstatic defense with harder learning on.
I can easily add some, but so far you are the only person to request it.
If I ever make a human-focused update, I probably add them. 
Am I really? I figured other people would have noticed they didn't really have joinable analogues for the other races' combat castes.
My suggestion then would be a State Army enlistment building with Armsmen to do melee stuff and Marksmen for ranged fighting along with of course, using gold to bulk-order shipments of equipment for your new State Infantrymen (which a small chance of not succeeding, to represent lost, stolen, or misfiled orders.)
Perhaps sets of armor divided into simple, basic, and elite (buying cheap sets of helmets, mail, and leather armor, fairly priced sets of full regular armor, and sets of very expensive/extortionately priced plate armor.) In addition to a bulk order of standardized bronze or iron spears, axes, and crossbows - the weapons of the common man. It'd also be a good money sink if you have everything you feasibly need but your militia/mineral wealth is lacking.
While we're on the topic of a human focused thing, I'd also advise having actual values instead of leaving the variable setting, probably with an emphasis on craftsmanship, commerce, and skill at arms (good products sell for more and good soldiers are needed to protect caravans and investments; the fact humans are also almost always at war with someone somewhere in a given world-gen would make that fit.)
