Hello, been away for the holidays have only just gotten to this post. On the subject of the Mongols, you might want to reassess them. The standard Mongol Army was organized into a decimal system, nine men and a commander, at every echelon all the way to the Tumen. The troops were equipped with Mail Armor, over silk undershirts--to allow anyone hit by an arrow to have the arrow removed by gently tugging on the uncut silk tunic. The horsemen had four horses per man, trained to run with the lead horse. The armaments were a mix of weapons: Long Range Bow, Short Range Bow, Sabre, and lance. The arrows used included incendiary, armor piercing, signal, smoke, and even explosive. The Mongols employed extremely sophisticated operational scale tactics--based on the great hunt.
The great hunt was organized on a baseline of over 150 kilometers wide, the entire Mongol Army participating. They would drive forward en mass, to trap every animal on the Steppes, encircling them and then killing all trapped predators at the end of the hunt--arranged for at a specific location. The entire army was controlled by a series of Arrow riders.
When Genghis Khan hit China, he had 100,000 troops, he conquered China, adopted their siege warfare technologies, and then used it to wipe out the Moslem Central Asian Empires. His sons extended his empire to Russia and Poland, and Hungary, reaching the Adriatic at one point. Later the Mongols invided the Abbasid Dynasty and wiped out the city of Baghdad, only being stopped by the Mamluk Army of Eqypt. Later the Mongol Lords of Persia--the Ilkan Dynasty, moved east into India establishing the Mugal Dynasty.
They had Chinese and Persian Engineers with them at Kiev, when the took that city of a quarter million in five days. They killed everyone in the city.
I think you would find a true mongol empire with high technology very formidable
