Great job, err.. "comrade"! I was impatient and didn't install properly, but only checked the civilopedia. Like most of the changes! Especially dating back the UHV conditions for the Maya (really, really hard to pull off before... ) among others. Many UBs also give a much needed shot in the arm for a lot of civs. However, there are a few things (might have more to do with the original modcomps for 2nd UUs and UBs): I find the Sepoy as an Infantry replacement a bit late. Also, the Kobukson only showing up with Chemistry... I don't know. Furthermore, most UUs are quite good, but I find the Ethiopian ones a bit generic and uninspiring. Surely there must be more information about Ethiopian military history around (not just the battle of Adowa etc)- if push comes to shove, why not use Civ5's Mehal Sefari. Dito about Naffatun for the Iranians... What about:

Furthermore, this might have to do more with my lazy way of installing the mod-mod-mod, but I noticed several naval units only have a movement of 1 ! First I thought this was intentional and Oil or Coal would enable movement only (now that would be a nice, if practically annoying idea for more realism), but then I figured out it was all across the board (incl. Ship of the Line, Man-o-War, but submarines were fine)- so I don't know what to make of this.
