Какое отношение это имеет к Украине?

It's the Warrior's Prayer by the Don Cossack Choir. The YouTube link is in the credits .txt file in the mod's package.

do you know what the name of the song that play when war declared.

Yep, update is out, everything is back in working order.

Thanks for bringing it to my attention Eris.

The Leaderscreen appears to be broken, Leader code refers to a different leader xml name than the one that's supposed to be used

Good mod, the Don region is a very important spiritual space for Ukraine and Ukrainians. Slava Ukraini. I'm actually learning Ukrainian right now, it's a very impressive language.

Thanks for the clarification, I was thinking one of the reasons they have unique armored units is because compliment the UA in later eras. I will definitely being trying out this civ. Slava Ukraini.

Hey Ghost, the UA effect only applies to UNITCOMBAT_MOUNTED, which is the Chariot Archer, Horseman, Knight, Lancer, and Cavalry, not armoured units. The Austin Armoured Car, imo, sooths that transition, but I believe the UA is interesting enough on its own. Fair enough if you have balance concerns, and I appreciate you asking the question.

Does the UA bonus apply to armored units too? I like the concept but I feel it's a bit weak if the UA becomes useless after the industrial era.
