To answer the banner issue, it's an issue of what information is blocked out. Typically, the space between the TOP SECRET and NOFORN is compartmentalized accesses that are required to view the document. Just because you hold a Top Secret Clearance and you are an American Citizen (the only people who are allowed to view NOFORN documents) doesn't automatically mean you can read this. You also must have a work related "Need to Know" reason to see this information. These are divided in a process called Compartmentalization and while the cover terms for these compartments are not, themselves, classified, they appear in the same document with information they handle, so this redaction prevents association of a particular program with a particular product that they produced.
So your information seems to be assuming that there will only be two sections of information in the banner. There are three.
The Clasification (CLASS) the Special Accesses (SAP) and the Dissemination (DISS). These terms are not official, I just don't want my examples to be official looking. These sections are separated with double slashes "//". So that a typical banner will look like this:
Additionally, if there is more than one piece of information in a section of the banner it will be noted by a single slash "/" such that:
CLASS//SAP/more SAP/One More SAP//DISS/really watch yourself DISS
As a final note, the CLASS will only have the phrases: UNCLASSIFIED, CONFIDENTIAL, SECRET, or TOP SECRET in its section. It will never have a single slash "/". Additionally, the DISS section will always start with either REL or NOFORN.
Finally, although rare to happen, if a classification has no SAP or NO DISS, it is skipped. So those banners read:
Since TOP SECRET AND NOFORN are visible in this, we can assume everything between those two phrases are SAP markings. Everything after NOFORN are additional dissemination controls.
Hope this revision helps explain why it's blotted out.
