Well, you have to keep in mind that compartments, from the way I understand them, are topical, or centered around the specific field they pertain to. Thus, the DOE and the DOD won't have the same compartments, and even the Army and the Navy won't have the same compartments.
This is, I believe, one of the reasons that intelligence sharing between agencies and the armed forces is so difficult. Some intel is compartmentalized in places that are inaccessible to another branch or agency, and changing the classification level or compartment of information is an extraordinarily inconvenient process.
The upside of this, however, is that we really do have a secure system for information
