I have searched for this on the german market , and I contacted the release company if this was still available see below correspondence:
According to this information, Rough Trade Distribution has the distribution of the Limited futurepak edition: Courage for truth
Editor:
Filmconfect Home Entertainment GmbH
Distribution:
Rough Trade Distribution GmbH
I would like to ask you if this Limited futurepak is still available for purchase?
this was their answer
Good day,
the publication was withdrawn by Filmconfect.
No publication in this form is currently planned.
so this means there was never an release of courage under fire Futurepak
