These articles are a few months old, but the latest news is that about 240 battle-damaged Leopard 2A4s, T-72s and T-64s have been repaired in Poland and sent back to Ukraine. On top of that, Poland donated 300 T-72s, 60 PT-91s and 14 Leopard 2A4s to Ukraine, so the total contribution is massive:
Poland has handed over the first batch of repaired Leopard tanks to Ukraine. The tanks were repaired at the Bumar-Łabędy plant.
