FM 31-28 (FOUO), Special Forces Advanced Urban Combat (1 December 1999), stands as a transitional doctrinal artifact. It captured the U.S. Special Forces community’s realization that the 21st-century battlefield would be increasingly urban, and that conventional infantry manuals were inadequate for 12-man teams operating autonomously. While restricted from public view, its influence is evident in post-9/11 SF urban tactics. The manual’s greatest legacy may be its emphasis on training partner forces in urban combat—a concept that became central to counterinsurgency in Iraq and Afghanistan.
Future research, pending declassification, should compare the 1999 manual with the 1995 draft (if any) and the 2006 revision to trace the evolution of Special Forces urban doctrine across the Global War on Terror.

The "FOUO" (For Official Use Only) marking is critical. This manual was not classified (No Secret/TS clearance required), but it was restricted. Why? Section 1-4 of the PDF explicitly states that the "Advanced" techniques regarding covert breaching (lock picking, defeating commercial security systems) and the specific employment of sub-lethal munitions in hostage scenarios were deemed sensitive. Releasing these specifics to the public, the Pentagon reasoned, would allow militias or terrorists to harden their positions against these specific SF techniques.

1. The Classification (FOUO): The marking "FOUO" (For Official Use Only) indicated that the document contained information that was not classified for national security reasons (like Top Secret) but was not intended for public distribution. This usually covered sensitive operational tactics, specific equipment capabilities, or details that could be detrimental to operations if widely disseminated. Today, while many FOUO documents are technically restricted, digital copies of this specific manual have circulated widely among military historians and enthusiasts.
2. Doctrine Shift: In 1999, the Army was transitioning from the open-field battles of the Cold War era to the "Three Block War" concept—where soldiers might be conducting humanitarian aid, peacekeeping, and lethal combat simultaneously within the span of three city blocks. This manual bridged the gap between traditional Special Forces doctrine and the reality of modern, non-linear urban battlefields.
The designation FOUO (For Official Use Only) is critical to understanding the nature of this document.
For a soldier or analyst in 1999, this meant the manual contained operational specifics—Tactics, Techniques, and Procedures (TTPs)—that the Army did not want readily available to potential adversaries.
