Ten tanks that are already in Ukraine have several minor faults. These problems are being rectified in Ukraine, writes the Minister of Defense of Denmark, Troels Poulsen, in the written briefing, the TV2 reports.

Another ten tanks have been handed over to Ukraine but are still in Poland. According to the information, two of these tanks have serious faults, Poulsen concludes.

On 19 September 2023, it appeared that ten tanks which were to be delivered from Germany to Ukraine, were rejected by Ukraine. The German media Der Spiegel revealed that the tanks were so worn out that they could not be used.
