## Organizational structure

The 528th Sustainment Brigade (SO) (A) consists of a brigade staff, a support operations unit, and three battalions: the Special Troops Battalion, the 112th Special Operations Signal Battalion, and the 389th Military Intelligence Battalion.

### Special Troops Battalion

The Special Troops Battalion (formerly known as the 528th Support Battalion (A)) provides rapidly deployable combat service support and health service support to ARSOF and consists of a headquarters company with an organic rigger detachment, a special operations medical detachment with four Austere Resuscitative Surgical Teams (ARSTs)—formally known as Special Operations Resuscitation Teams (SORTs)—the 197th Special Troops Support Company from the Texas Army National Guard, and 1/528th Forward Support Company from the West Virginia Army National Guard.

### 112th Special Operations Signal Battalion

The 112th Special Operations Signal Battalion (A) is the Army’s only special operation airborne signal unit. The 112th specializes in advanced communication while employing and developing innovative telecommunications technologies to provide both Army and Joint special operations task force commanders with secure and nonsecure voice, data and video services. The 112th's signals expertise allows ARSOF to "shoot, move and communicate" on a continuous basis. Signals soldiers assigned to 112th are airborne qualified and are taught to operate and maintain a vast array of unique and specialized communications equipment not normally used by their conventional counterparts. To meet the needs of ARSOF and SOCOM, the 112th can be deployable on a moment's notice with an authorized strength of five companies: a headquarters company, a Theater Signal Support Company with six geographically focused signal support detachments, and three general signal companies.

### 389th Military Intelligence Battalion

The 389th Military Intelligence Battalion (SO) (A) "conducts command and control of multi-disciplined intelligence operations in support of the 1st SFC, component subordinate units, and mission partners." On order, it deploys and conducts intelligence operations as part of a special operations joint task force leveraging the capabilities of its three organic companies: a headquarters company; an Analytical Support Company with a cytological support element and five geographically aligned regional support teams; a Mission Support Company with a Processing, Exploitation, and Dissemination (PED) detachment, a HUMINT and GEOINT detachment, and operations the Special Warfare SIGINT Course for the ARSOF community; and an additional PED detachment stationed at Fort Gordon.
From 2015 to mid-2019, the unit operated under the ad hoc name of 1st Special Forces Command Military Intelligence Battalion (A). To avoid being assigned the 'next available' number, the Department of the Army Force Management, U.S. Army Center of Military History, and USASOC History Office worked with battalion leadership to determine a unit designation that reflected a legacy of military intelligence support to ARSOF and carried forth the wartime honors of a past military intelligence unit. In July 2019, the 389th Military Intelligence Battalion (A) was activated and provides 1st SFC with a deployable, operational-level intelligence capability with the motto "Illuminate to Action!".

### Support Operations

Support Operations embed in each regional theaters' staff to support planning and coordination with theater Army, Special Operations Command and Army Special Operations Command to ensure support during operations and training. As a theater Army staff member, these officers and non-commissioned officers' knowledge of theater-specific requirements and capabilities assist units in coordination with the theater. Support Operations consists of four detachments: current operations which manages five geographically aligned ARSOF liaison elements, a future operations detachment, a commodity managers detachment, and an ARSOF support operations element.
