Will steel prevail against flesh? The steel is in the Leopard 2, Abrams, and Challenger tanks now on their slow way to Ukraine. The flesh is the hundreds of thousands of conscripted Russians Putin is prepared to throw at them this year in a new offensive.

The German built Leopard 2 A6 is not “just” expensive, it’s one of the best battle tanks in the world – some say the best.
