Well as far as I know (and I have been to the Topkapi museum in Istanbul+plus reading+ dad is Turkish), all of the above are mostly accurate, just a fun fact Asker means soldier in Turkish. But unfortunately BC 3.0 from what I've read here on the forums will not include the ottoman era, although Turkish military systems are quite similar from dynasty to dynasty and empire to empire, with mostly just name changes, and IMO BC has done quiet a good job at reflecting them
But I don't agree with the comparison of the askeri and timar holding classes with European feudal lords. Although similar systems, timar was considerably different to a feudal fief. (And the role of Askari was highly controlled by the centralised government) The main difference being that the timar was owned by the central government and could be (and was!) taken back if the sipahi did not comply with his duties. Which other then military, included working the timar. The law was that if the timar was not worked for 3 years straight it would be taken back (arguably the most important aspect of the timar, since this law ensured the continuity of production).
Anyway before I go off on a random rant I would just like to say that keep reading the book, it has good stuff
