According to this article, the German Army has about 850 Leopard II tanks.

And they list 101 as operational. Maybe they have to share tracks and engines....
How many tank chassis they have is one thing; how many are in a good enough state of repair to go into battle and be effective for more than a few minutes is another.
I read only about 4-6 months ago that the Krauts had about 200 operationally-capable tanks, and unless there is a really compelling reason, something like that doesn’t get fixed that quickly. Maintanence and repairs of any vehicle isn’t very politically sexy, and I don’t see that being a huge priority in a nation that is just fine with hundreds of thousands of Moslems coming in at any old time, getting on welfare and raping dozens or more German girls and women each week.
