I started that book, got about 60% of the way through, and had to put it down. It seemed like Jocko was re-teaching the same lesson over and over again from slightly different angles.

Maybe I missed something big, but that's just the way it felt to me.

I think you're missing a lot. It might seem repetitive because in almost all the stories Jocko is practicing almost all the principles at the same time, but in different chapters he definitely teaches different lessons.
