The General Staff had four main operative departments in charge of mobilization and organization of military units, information gathering, military operations and education, and logistics (supply, communications, transport). The staff was severely understaffed. For example, at one point, the department in charge of planning military operations during the Lithuanian Wars of Independence had only three officers. Therefore, it could only gather information and planning of operations fell to the commanders of the military units. Only one officer, Konstantinas Kleščinskis who joined the Lithuanian Army in May 1919, had general staff education or experience. That is because after the Uprising of 1863, Lithuanians were not considered reliable and were not admitted to Russian military academies. Additionally, the staff saw frequent leadership changes – in four years between November 1918 and October 1922, the staff was commanded by eight different chiefs. As a result, many operations during the Wars of Independence were poorly planned.
