7 out of a total of 40 operational ones that the Bundeswehr has, and these 7 were only available because they had just come out of maintenance.
Massively criticising Scholz is certainly not the worst thing one can do and this comment "Germany will never forgive Ukraine for resisting the invasion" is to be understood as a sarcastic comment in the direction of the politicians who believed that Ostpolitik was only Russia policy and that Putin and Russia could be integrated and "civilised" through understanding and economic interdependence.
This has led to such great deeds as the Minsk Agreement and to Steinmeier being deeply offended because he simply cannot understand that this agreement, which he negotiated in large parts, must be seen as the trigger for today's war.
You simply have to realise that the Bundeswehr is standing there with its trousers down. Here are a few figures from the year 2020, which will not have changed much in 2021 or even now, because the figures were the same in previous years.
Of 263 active Leopard 2s (there should be 328 ), just 43.7% were operational.
Of 343 Puma infantry fighting vehicles, 29.7% were operational,
Of 79 NH 90s, 23.0%,
and of 51 Tigers UHT, 18.0%.
Of 120 or so PzH 2000s, 40 are operational, about 30%.
In fact, the Bundeswehr can hardly hand over any more equipment because it would then no longer have the equipment promised for the VJTF operationally.
We are talking about an army that in the last few years has had to borrow personal equipment like NVGs or sleeping bags from all over the Bundeswehr to get about one battalion operational.
So it is down to the industry and there the fact is that all the other stuff you mention, Marder 1A3, Gepard, Leopard 1, has been in storage for ages with the industry, the manufacturers, who have bought these vehicles back cheaply and who have not maintained them or kept them operational.
Of course, the government would have had to ensure in February that the industry begins to make these vehicles operational, but again that did not happen and this is a huge mess and the behaviour of Scholz and the SPD do not make it better.
Now there is the problem that the industry, which also has only a certain number of personnel and means of production can only make a certain number of vehicles operational.
You don't get rid of 30 years or more of neglect, bad planning, total ignorance and indifference with a snap of your fingers.
Too little, too late is probably the best way to describe the situation.
I honestly can't tell what Scholz actually thinks or wants to do now, I've seen logs that had better communication skills than the man, plus he is obdurate and stubborn and has false pride.
He can't necessarily be blamed for what should have happened in 2014 at the latest, namely breaking away from dependence on Russia and diversifying, because a large part of this is really Merkel's fault, but that's also more of a footnote. He should have started when his government came into office.
The man is only capable of very limited reasoning, and that is probably one of his biggest problems.
