First Polish Leopard 2 tanks delivered to Ukraine, defense ministry says

Leopard 2 is a modern, well-protected main battle tank with good sensors,” Jack Watling, senior research fellow in Land Warfare at the Royal United Services Institute (RUSI), told CNN. “It was originally designed to be maintained by conscripts and is therefore simpler to keep in the fight than some other NATO designs like the Challenger 2. There is also an existing production line to keep Leopard 2s supplied with spare parts.”
