If Switzerland wouldn't just hoard their equipment but use it to help countries who need help, Ukraine could get many more Leo 2s. Switzerland alone has still over 220 of them and they will just never use them. What are they supposed to do? Defend Switzerland? Countries around Switzerland defend Switzerland (also a reason they don't need to be part of NATO) and if some enemy would really be at their boarder then it would be too late for them.
Too bad it takes ages nowadays to get new equipment when you order it. Germany ordered 18 of the new Leo 2 A8 but it will take until 2025 before they get the first lol. I also don't understand why you only order the amount you have to replace. I would really appreciate if Ukraine could get some new tanks every month from now on and not one package and that's what they have to live with.
How long are the 60 or something Leo 2 and some Challenger 2 supposed to be enough? Some will get destroyed and they also need maintenance obviously. Especially modern tanks need so much maintenance that they are probably less in use as in some factory so that you also need some for rotation.
