What sort of structure and tactics could be found in a 18th or early 19th century Ottoman army?

Did the Ottomans adopt the precision-drilled line infantry formations employed by the European powers? I know that the Ottomans were famous for their Bashi-Bazouk irregulars (thanks, Captain Haddock!), but how did their regular infantry operate? Did they have special heavy infantry units, similar to western Grenadiers? How was the army organized - regiments, battalions, and the like? Or more ad-hoc?

Follow-up: did they ever adopt the "core" system that Napoleon adopted, from which all of Europe followed?
