Kubuś (Polish for "Little Jacob") is a Polish improvised fighting vehicle used by the Home Army in the Warsaw Uprising during World War II. The single vehicle was built in secret to function as an armoured car and armoured personnel carrier for assaults by the Home Army, where it suffered damage and was abandoned after two weeks of service. The original Kubuś vehicle survived the war and is on display in the Polish Army Museum, while a full-scale replica was built for the Warsaw Uprising Museum and frequently takes part in various open-air festivals and reenactment shows.
