Field Manual (FM) 3-05.230, Special Forces Tactical Facilities, supports key United States (U.S.) Army Special Forces (SF) doctrine. An SF tactical facility (TACFAC) is defined as any secure urban or rural facility that enables Army special operations forces (ARSOF) to extend command and control (C2), provides support for operations, and allows operational elements to influence a specified area. SF TACFACs include a variety of secure locations for SF operations, including (but not limited to) firebases, camps, and team houses. This FM presents the details of the three phases of SF TACFAC development in an order that the SF Soldier should expect to encounter them-initial, temporary, and permanent. Additionally, this FM discusses in sequence planning, design, construction, operations, sustainment, funding, and transfer of authority. The primary audiences of this FM are the commanders, staff officers, and operational personnel of Special Forces operational detachments A (SFODAs), Special Forces operational detachments B (SFODBs), and Special Forces operational detachments C (SFODCs).
