To cut down on squabbling, I'm not announcing what unit I'm doing or what order I plan to be doing them in.
I would, however, like some advice on which units should get which weapons.
The Zulu mounted warrior will get a spear. The gatling gun elephant... well, duh. Velites too. Hwarang Archer, though he has no bow, is also pre-chosen. Archer is decided too as is the Chinese unit in Row 2, slot 2, which will be the firelancer.
The rest are something of a toss up. The Qin soldier in Row 2, Slot 1 in the pictures I have could have a crossbow, sword, spear, or pike.
Now, we already have possible fill-ins for a Chinese Swordsman and Medieval Infantry with the Shang footman and Chinese Swordsman made by utahjazz. So I'm thinking like maybe we should go for a crossbowman or spearman. If the spear were short enough, it could work either as an offensive or defensive infantry unit.
As for the Koguryo-era unit in Row 1, Slot 4, he could be a number of things too, but he doesn't seem beefy and armored enough to work well as a Swordsman or Medieval Infantry, so I think I'll make an archer out of him, or a spearman.
The Choson soldier is another tough one... because in terms of Civilization, by the time the Choson dynasty comes around, we're moving out of the "middle ages" and into the gunpowder era. He could work well as a Man-at-arms substitute for Kal-El, but in vanilla civ, even with the Med. Infantry, he's going to be a gunpowder unit. He could, in fact, serve well straight up past Riflemen though not Infantry. But in reality, these kinds of soldiers didn't fight much (or for a large portion of the Hermit Kingdom's history AT ALL) with gunpowder weapons.
And there are some cavalry on the way for Korea and China, but their roles are pretty much fixed regardless of the weapons in their hands.
