The military need it is being built for is "casualty evacuation and cargo resupply". The only thing really distinctly military with regard to these is that the military happens to be a large single customer who, if they purchase it, will secure the future of the company in one fell swoop.

Which is one reason to focus on military first.

Its not really "reuse for different purpose" when you also sell the same thing to civilian customers who have the same kind of needs.
