From the end of 16th century there were two hetmans in the Grand Duchy of Lithuania and two hetmans in the Crown: a Field Hetman and a Great Hetman (sometimes translated as Grand Hetman). So there were in total four hetman titles: Great Crown Hetman, Field Crown Hetman, Great Lithuanian Hetman and Field Lithuanian Hetman. During joint military operations of the Crown and Grand Duchy of Lithuania armies, the Crown Great Hetman usually was considered superior to others hetmans and served as commander-in-chief if the war actions ran along the borders of the Grand Duchy and vice versa.
