joint ceremony at Fort Bragg on 3 December 2018. 2nd SFAB deployed to Afghanistan in February 2019. 3rd SFAB activated at Fort Hood on 16 July 2019; 3rd SFAB will relieve 2nd SFAB in Afghanistan for the Winter 2019 rotation. Security Assistance is part of The Army Strategy 2018's Line of Effort 4: "Strengthen Alliances and Partnerships". The Security Assistance Command is based at Redstone Arsenal (but the SFAC is based at Fort Bragg). Army Field Support Brigades Army Field Support Brigades (AFSBs) have been utilized to field materiel in multiple Combatant Command's Areas of Responsibility (AORs). Initially 405th AFSB prepositioned stocks for a partial brigade; eventually, the 405th was to field materiel for an ABCT, a Division headquarters, a Fires Brigade, and a Sustainment Brigade in their AOR, which required multinational agreements. Similarly, 401st AFSB configured materiel for an ABCT in their AOR as well. The objective has been combat configuration: maintain their vehicles to support a 96-hour readiness window for a deployed ABCT on demand. In addition, 403rd Army Field Support Brigade maintains prepositioned stocks for their AOR. Command headquarters Below the Combatant Commands echelon, Division commands will command and control their combat and support brigades. Divisions will operate as plug-and-play headquarters commands (similar to corps) instead of fixed formations with permanently assigned units. Any combination of brigades may be allocated to a division command for a particular mission, up to a maximum of four combat brigades. For instance, the 3rd Infantry Division headquarters could be assigned two armor brigades and two infantry brigades based on the expected requirements of a given mission. On its next deployment, the same division may have one Stryker brigade and two armor brigades assigned to it. The same modus operandi holds true for support units. The goal of reorganization with regard to logistics is to streamline the logistics command structure so that combat service support can fulfill its support mission more efficiently. The division headquarters itself has also been redesigned as a modular unit that can be assigned an array of units and serve in many different operational environments. The new term for this headquarters is the UEx (or Unit of Employment, X). The headquarters is designed to be able to operate as part of a joint force, command joint forces with augmentation, and command at the operational level of warfare (not just the tactical level). It will include organic security personnel
