German and Slovenian governments have come to the following agreement: Slovenia gives to Ukraine Warsaw Pact tanks, in return Germany provides them with modern Leopard 2 tanks, Marder infantry fighting vehicles and Fuchs wheeled armored vehicles, FAZ news agency reports. According to them, Ukraine is about to get T-72, however, they stock Yugoslavian M-84, which are licensed copy of the Soviet T-72M1. According to The Military Balance for 2021, Slovenia has 14 units of M-84 tanks in service and other 32 are in storage.

It is noted that Berlin resolved to switch to a new scheme of military aid to Ukraine, which is called “ring exchange”: instead of directly supplying own armament to the Armed Forces of Ukraine, Germany will pay other countries to send their own Soviet-era armament to Ukraine. As a “compensator”, Germany will provide “third-party countries” with own weapons.
