Fm 31 28 Fouo Special Forces Advanced Urban Combat 1 December 1999 25

By 1999, the U.S. Army recognized that future wars would not be fought solely in the German Fulda Gap or the deserts of Iraq. Instead, conflicts were moving into sprawling megacities: Mogadishu (1993), Grozny (1994-95), and the ongoing Balkan peacekeeping operations. For Special Forces, whose primary mission was Unconventional Warfare (UW) – training guerrillas in denied territory – the urban environment was a nightmare. How do you run a resistance cell in a city of 2 million, under pervasive surveillance, with vertical terrain and civilians everywhere?

Item 25 in a battle drill table: At 25 meters or less inside a building, SF operators were to transition from carbine to pistol or edged weapons due to retention risks. This was a radical departure from conventional room-clearing (which allowed rifles at all ranges).

Below is a concise, structured study/reference guide that covers core topics, structure, and practical takeaways from FM 31-28 (Special Forces Advanced Urban Combat, 1 December 1999). Assumes the manual’s focus on tactics, planning, and small-unit actions in urban environments.

The document was marked FOUO, not Secret or Top Secret. FOUO is a handling caveat, not a classification. This meant the tactics, techniques, and procedures (TTPs) were sensitive but did not involve cryptographic or intelligence sources. According to declassified records, FM 31-28 was restricted because: By 1999, the U

Because foreign intelligence services could use this information to harden their cities against SF infiltration, the Army restricted distribution to Special Forces units, SWC instructors, and certain JSOC elements.

If you possess a physical copy of FM 31-28 (FOUO) dated 1 December 1999, it is likely a controlled item. According to AR 25-55 (Department of the Army Freedom of Information Act Program), such outdated FOUO documents should be destroyed or decontrolled. However, many veteran SF operators retained personal copies – some of which have appeared in online auctions, only to be swiftly removed.

The “25” in your query remains a tantalizing clue. It might be a paragraph about the 25 most dangerous intersections in an urban fight, a figure diagramming 25 ways to scale a wall, or Annex 25’s “Assault on a Vertically Partitioned Target.” Below is a concise, structured study/reference guide that

Regardless, FM 31-28 (FOUO) stands as a milestone: a manual written in the brief twilight of the pre-9/11 world, anticipating the urban battles of Fallujah, Mosul, and Mariupol. It was a docent for the dark corridors and high rooftops where special forces still fight – one mousehole at a time.

Title: A Deep Dive into FM 31-28: Special Forces Advanced Urban Combat (December 1999) acceptable for M4 with suppressor).

Introduction In the landscape of late 20th-century military doctrine, few publications were as anticipated or as necessary as FM 31-28 (ARC): Special Forces Advanced Urban Combat. Published on December 1, 1999, and marked FOUO (For Official Use Only), this manual represented a critical pivot in United States Army Special Forces (Green Berets) training.

Coming off the heels of operations in Somalia (Mogadishu) and preparing for the conflicts of the 21st century, this manual bridged the gap between traditional wilderness guerrilla warfare and the realities of modern, built-up environments.

Note: While the document was originally classified FOUO, many of its specific tactical techniques (TTPs) have since been superseded by modern doctrine (such as ATP 3-21.8 or TC 3-21.76). This article discusses the manual from a historical and doctrinal evolution perspective.

The manual introduced the concept of "acoustic shadowing" – using the echoes between buildings to mask movement. It included decibel tables for suppressed weapons vs. background urban noise (e.g., a subway train passing at 30 mph generates 95 dB, acceptable for M4 with suppressor).
