Generalizations.
Helping idiots hate other idiots since people have existed.
I think they didn't use navy ranks because most people are not familiar with them. Most players are familiar with the Marine ranks, however.
Spartans of part of the Naval Special Warfare Command, and hereby part of the navy and assigned Naval Ranks.
However, the player is not technically an official, permanent Spartan; one could hypothetically say he is just a marine. Perhaps that is why it makes more sense that they used Marine ranks in that sense.
