Petyhorcy
Petyhorcy (singular: Petyhorzec, Latin: pientho-horcensis, Lithuanian: Petihorai) was a type of regular medium-armoured light cavalry exclusively in the Grand Ducal Lithuanian Army during the 17th and 18th centuries. The petyhorcy are viewed as the Lithuanian equivalent of the Polish Armoured Companion, or as a cavalry type that was between the Winged Hussars and the Armoured Companion.
