I think Rater's ideas sound fun.
I can also see benefit of this kind of mission.
Like street gangs or something.
I already established dropouts from the academy as criminals, so it can work.

About mission rankings-
Realisticly, I dont think it always cut and dry.
Like with Zabuza's mission.
Also, I served both my duty service, and sort of serve on the reserve forces, of assumingly huge and modern military.
But orgnizations, have lot of chaotic stuff happens.
Like,you can meet soldiers from other unit in your base, and no one(including them) is sure why they are there.
People "fall between the chairs" as the speak.
I seen Commando soldiers doing crappy missions of small fry like me, and in actual military operation, small fry like me on the front.
So D or C isn't a biggy for me.

Also also.
