guys, i can give you information you want about ottomans; i'm Turkish and i have seen the lessons of history about Ottomans in school, for many years.İ have a lot of images about them, or information.so ask about them to me before doing something about them.
for example; the best cavalary of ottomans weren't the "sipahi's", the best cavalary of ottomans were "Deliler(deli's)". deliler were the soldiers that goes first to battle, they were running upon their ennemies without thinking.
the jannisarys were a big group, at first they were the best soldiers that a country have; but later, they started a few riots; and the most suprising one; they have killed a sultan!(the sultan was the genç osman ( young osman)(3.osman))
i can edit your ottoman troop tree, if you wish of course
