Methods of handling fatal funnels (doorways and hallways where troops are most vulnerable).
The manual divides urban operations into distinct, highly specialized disciplines that Green Berets must master to survive and win in close-range environments. 1. Advanced Urban Marksmanship

FM 31-28 emphasizes the importance of advanced planning, coordination, and integration with other military units and civilian agencies in urban combat operations. Special Forces operatives must be able to navigate complex urban terrain, gather intelligence, and engage hostile forces while minimizing collateral damage and civilian casualties.
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 in urban combat—a concept that became central to counterinsurgency in Iraq and Afghanistan. Special Forces operatives must be able to navigate
Although the full PDF is restricted, declassified training materials, after-action reports, and subsequent doctrine (e.g., ATP 3-06.20, 2020) allow reconstruction of FM 31-28’s likely core topics:
Below is a based on the known context, doctrinal lineage, and historical significance of this specific field manual. The paper treats the document as a case study in the evolution of U.S. Special Forces urban warfare doctrine at the turn of the 21st century. Core Tactical Pillars of FM 31-28
Today, much of the 1999 doctrine has been superseded by newer techniques (such as "Limited Penetration" over "Immediate Entry"). However, FM 31-28 remains a "holy grail" for military historians and tactical enthusiasts because it captures the peak of late-90s Special Operations logic.
The manual structures advanced urban combat training around a progressive methodology. Detachments advance from individual fundamentals to coordinated, multi-team direct-action operations. 1. Advanced Marksmanship Fundamentals
FM 31-28 codified the course. SFAUC is a rigorous training block managed across individual Special Forces Groups. The 1999 manual shifted the tactical focus from blunt force to precision, flexibility, and speed. It recognized the city not just as a collection of buildings, but as a complex, three-dimensional ecosystem requiring unique skills. Core Tactical Pillars of FM 31-28
