The 7TP (siedmiotonowy polski - 7-ton Polish) was the Polish light tank of the Second World War. A development of the British Vickers 6-ton, it was significantly better armed than its most common opponents, the German Panzer I and Panzer II. A standard tank of the Polish Army during the Polish Defensive War of 1939, its production never exceeded 140 vehicles. All 7TP tanks took part in combat in the Polish Defensive War of 1939. It is to be noted that twin and single turret variants had no specific designations. In some modern books they are designated with abbreviations: "7TP dw." and "7TP jw." (Polish abbreviation for jednowieżowy - single turreted, and dwuwieżowy - dual turreted). However, these were not the official names of the variants and are used for simplicity's sake only.

Most of them were attached to two light tank battalions (the 1st and the 2nd). The remaining tanks, that is the ones used for training as well as tanks that were finished after the outbreak of the war, were used in an improvised tank unit fighting in the defence of Warsaw. Although technically superior to any of the German light tanks of the era, the 7TP was too scarce to change the outcome of the war.
