Thanks! I already have all needed information about (nominal at least) organization of the Ottoman army of that time, which consisted of 6 corpses and auxiliary contingents, mainly from Egypt and Tunisia. I have also list of regiments, who defended Kars fortress in 1855, so if I won't find list of regioments or at least corpses, who were in the Crimea, I'll take numbers for regiments-in-game from there, especially since I'm planning to make map of siege of Kars.
Or maybe I'll name units just like "Turkish nizam infantry" (regular infantry), "Turkish redif infantry" (reserve infantry), "Turkish chasseurs", "Anatolian infantry", "Egyptian infantry", "Tunisian infantry" etc.
