Heavy European tanks and armored vehicles have faced operational problems in Ukraine, often getting stuck in the mud or running out of fuel. In addition, European tanks have proven vulnerable to enemy fire. In many cases, Germany's Leopard tank – a tank that was considered superior to the Abrams – has not performed well.

The Russians have already destroyed around 15 Leopards using a variety of weapons ranging from artillery to rockets launched by helicopters to drones such as the Lancet. Billed as the next great thing to help Ukraine win the war, Leopard has proven a failure.
