Yes but remember that was the point.
The career and trained militaries were spending most of their time schooling young people and were not focusing on capabilities. This is why most countries put an end on that nonsense.
So right now you can be sure an enormous amount of personnel in the German army switched focused on running this new "Voluntary service". A voluntary service which will produce at best 1% of workable soldiers.
This makes no sense.
