You're right about secret level work being boring, it's normally related to stuff like the exact time and location of a military flight or convoy, or other things that can impact people at a smaller level, but aren't really dangerous to the nation as a whole if they get leaked. I think I only ever saw something marked as confidential one time while I was in the military; general information was normally unclassified and anything that was deemed sensitive was bumped up to secret because it was easy to get for anybody that had a need-to-know.
