This should be checked by someone who understands the composition of eastern armies (Persian, Indian, Chinese, etc) better than I do.
Explanation of change: Musketeers, pikeman etc were totally useless against properly leaded and trained cavalry, up to some 1620s, and cavalry in eastern style still was able to defeat infantry surely during napoleonic wars (i don't know any such accidents later).
Anyway, i feel that changes i did should be reworded, but i am a bit tired and i will work on it later, unless someone else will eb able to came with inflammatory sentence which would reflect difference between Western and Eastern cavalry
