On Friday, Prime Minister Mateusz Morawiecki reported in an interview with Canadian tv that Poland has already transferred 250 T-72 tanks to Ukraine and is ready to deliver another 30 T-72s, 30 PT-91s and 14 Leopards 2. This message clearly indicates that the era of T-72 tanks in the Polish Army is passing. Thanks to the open archival sources and the open Polish data transferred to the UN Conventional Arms Export and Import Register, we will effort to recreate part of the past of the T-72 in Poland. Part of, due to the fact that inactive not all papers are available.
