It's sad to say, but I feel it has to be mentioned that Leo 1 tanks are nothing like Leo 2. Of course, 49 tanks are always better than 0 tanks, but European countries should pull themselves together and get more Leo 2s to Ukraine asap. If (when) Ukrainian forces are going to spearhead through a breach or weakness in Russian defences, a large number of high quality tanks are going to be needed.
It seems ukraine didnt/doesnt use the given tanks as they were (perhaps too quickly) taught, so the quality of tanks is not as important as the number of tanks.
