In that case the roster is quite simple , but I have to divide it into 3 periods which can be treated as early, medium and really advanced units. Anyway here it is: The earliest times where the army was still with many old Slavic traits - quite weak cavalry and good light infantry. Cavalry Jazda Pancerna ( Mail-clad Horsemen) - Duke's/King's early knights - not so powerful as real knights, but more disciplined, Infantry Lucznicy ( Archers) - bowmen were considered very dangerous part of early Polish armies, were armed with dangerous longbows, but it required some time to train such in later periods, Tarczownicy - ( 'Shielded') - spearmen with spears, light infantry, but with powerful pounch and some decent defence, Medium period - army was westernised with all the usual stuff like Knights etc, Cavalry Rycerze ( Knights) - nothing unique, Mazowiecka Konnica ( Masovian Cavalry) - medium-light cavalry with mch similarity to Lithuanian and Rus cavalry (cavalry pavise shields), agile and hard-hitting were not equal of the powerful knights, but had enough power to deal with most enemies on their own, Infantry Kusznicy ( Crossbowmen) - also as usual, Wlocznicy ( Spearmen) - as above, Advanced units - late XVth century Polish army was slowly abandoning old knightly cavalry and similar supporting infantry - the core of the army was the new professional infantry and cavalry. Army was created after suprising defeat from the Teutonic Order's army at Chojnice and started virtually undisturbed 200 years long period of victories over all manner of foes. Cavalry Kopijnicy ( Lancers) - heavy Men-at-arms armed with long lances, warhammers and swords and equipped with excellent gothic armour. Strzelcy ( Shooters) - crossbow (later bow and handgun) armed cavalry supporting Kopijnicy and lighter mobile cavalry with their mobile firepower. Racowie - light cavalry armed with lances and curved shields - early Hussars who slowly replaced Kopijnicy in later decades. Infantry Draby - Hussite style infantry armed primary with crossbows, handguns and bows with over 60% in each ten equipped missile weaponry with at least one pavise armed and one heavily armoured pikeman. Polish infantry were mainly from Bohemia providing much of the employement for Hussite mercenaries making the wars in later XVth century the last Hussite wars but they were used almost only to provide firepower, in sieges, in garrison duties and sometime to clear difficult terrain in close combat, cavalry was the hammer of the army - infantry remained it anvil. Ships and artillery Basically the same as in western europe, but with 2 notes: - galleys were not used, but other Northern and Baltic Sea ships, - Poland had one of the most modern artillery train in the late XVth century - useful to besiege numerous Prussian castles of the Teutonic Order and also started using artillery very quickly with several pieces in early XVth century, That shouldbe good enought.
