There is also the false impression,
pushed by some weapon dealers (in German), that there are 'hundreds' of Leopards available. This is nonsense. Not every Leopard is like the other. The most standardized variant is Leopard 2A4 one. In the end Ukraine could receive may be 50 of those. The current German standard tank is the Leopard 2A7 which had three upgrades since the A4 version came out. Various countries have versions in between, often with their own upgraded gun control and communication systems. It would not make any sense from a training and maintenance point to give Ukraine a smorgasbord of various Leopard types. The logistics to support those would immediately become unfeasible.
There are also other issues. Soviet era tanks have a weight of about 40 metric tons. All he 'western' Abrams, Leopard, British Challenger and French Leclerc main battle tanks have a battle weight in the 60 metric ton class. I doubt that Ukraine rural roads and bridges were constructed with such tanks in mind. What use is a tank when you can not move it around without destroying your own supply routes?
There is also the important issue of training. This does not only include the technology of the tank but its tactical use in the field. The Turkish experience in Syria showed that bad tank tactics inevitably lead to
bad outcomes, no matter how good the tanks are.
