As far as I'm concerned, "Kadett", in the Prussian army, is the rank of a soldier whose primary aim is to obtain the rank of officer. I have almost never seen any of the Prussian regiments use the Kadett rank as the "starting" rank.
Furthermore, Garde Füsilier is not considered a rank, it is a separate infantry unit of the Guards Corps that used its own ranking system. In fact, I'm not quite sure if anyone other than me uses Garde Füsilier as a rank in their system. It's been introduced by me as more of an honorary title.
Regardless, good luck with implementing it in your ranking system.
I would also add that some of the abbreviations are inaccurate, but perhaps it is more of a matter of preference.
Forgive my intrusion.
