All eighteen Leopard 2 tanks, which Germany promised to hand over to Ukraine, have been transferred to the Ukrainian side.

According to Spiegel, the last tanks were taken out of Germany at the end of last week and were recently handed over at the Ukrainian border.

In addition to the Leopard 2, Germany also sent to Ukraine about 40 Marder infantry fighting vehicles promised earlier. The German government keeps the exact route of arms deliveries a secret for security reasons.

According to Spiegel sources, Ukraine has received Leopard tanks with "a large package of weapons and spare parts."

The Bundeswehr has been training Ukrainian soldiers to use complex weapons systems under an accelerated programme in the past two months. Also, Ukrainian technicians, trained by technical service specialists from among German military personnel, have arrived in Germany.

Leopard 2 is considered one of the most modern main battle tanks on the world arms market. It outperforms Russian tanks mainly due to its more powerful firepower, which usually allows it to destroy enemy targets with the first shot.

The challenge, however, can be the system's complexity, which requires very intensive maintenance. Therefore, Germany wants to open a maintenance and repair center in a country neighbouring Ukraine.
