Information Systems Engineering Command (USAISEC)

The United States Army Information Systems Engineering Command (USAISEC) is located at the foot of the Huachuca Mountains in Fort Huachuca, Arizona. Is has the primary mission of system engineering and integration of information systems for the U.S. Army. This mission includes the design, engineering, integration, development, sustainment, installation, testing, and acceptance of information systems. USAISEC provides matrix support to the Program Executive Officer and Program Manager structure for systems engineering and integration of assigned information systems.

The U.S. Army Information Systems Engineering Command (ISEC) is headquartered in Greely Hall at Fort Huachuca. This command carries out important roles in the Army's information mission area. These functions include engineering, installing, quality assurance testing, and developing software for the diverse communications and automation systems throughout the Army. The soldiers and civilian employees of ISEC have frequent opportunities to travel to places around the world to complete their mission of providing "information for decision."

The ISEC, as headquarters of a worldwide command, has field commands, engineering offices, and software development centers located around the continental United States. The command's elements at Fort Huachuca include ISEC Headquarters and nine directorates, a Software Development Center, and the U.S. Army 504th Signal Battalion.

Each of these elements draws on the highly educated and trained electronics engineers, communications specialists, computer hardware and software experts, and a variety of skilled support and administrative personnel. The functions of ISEC at Fort Huachuca are briefly highlighted below. ISEC engineers and directs the installation of specialized electronic systems throughout the world. These range from the exotic, such as satellite earth terminal installations (for all military services), to the commonplace, such as television and radio broadcasting stations.

To succeed, ISEC engineers must know exactly (to the last foot of wire, nut, or bolt) what is needed to accomplish any given mission. They must identify and specify the necessary equipment for each new project. ISEC engineers have the opportunity to travel while working on their projects, spending approximately 30 percent of their time at locations away from Fort Huachuca.

ISEC also plans and executes the test programs associated with all hardware and software systems scheduled for deployment in the Information Mission Area (IMA). These range from supercomputers to facsimile to satellite voice and data transmissions and Standard Army Management Information Systems. They also perform periodic technical evaluations of those systems that are operated and maintained by elements of the Information Systems Command. Mission accomplishments requires a travel-intensive activity program for its military and civilian members.

The Software Development Center-Huachuca (SDC-H) is one of several software development centers within the ISEC. This center performs as the principal Army developer of automated telecommunications software and special communications support systems. The SDC-H supports approximately 800 Army, Air Force, and Navy telecommunications sites around the world.

As the Army moves more and more into the age of automation, the ability of computer systems to automatically share information and processing power has become a critical need. The integration of personnel, logistics, financial, command and control, and communications systems is the mission of the Information Systems Directorate. The integration engineers ensure that, as information processing and transmission systems are fielded, they will inter-operate in the integrated IMA while employing proven standards.

Headquarters ISEC also provides corporate simulation and modeling support. It conducts system performance analyses, cost/performance tradeoff analyses, and survivability and risk analyses. It also prepares technical analysis cost estimates and performs independent evaluations for IMA systems.

The 504th Signal Battalion installs communications-electronics and automation systems worldwide. This global mission encompasses a variety of communications media, which include line-of-sight microwave, satellite earth stations, fiber-optic cable systems, and telephone exchange equipment. The battalion also installs a variety of data and automation systems and equipment. Battalion personnel accomplish their mission through a travel-intensive program while assigned to the organization. Their work, almost exclusively at places outside the Fort Huachuca area, keeps most members of the battalion on the road approximately two-thirds of their tour with the unit. In addition to installation responsibilities and requirements, the 504th also de-installs obsolete systems and rehabilitates others under various system upgrade and modification programs.

In 1968 the U.S. Army Communications Engineering and Installation Agency (USACEIA) was activated. It's primary functions were radio propagation, installation, and construction. In 1970 it was given the added mission of responsibility of telecommunications engineering and evaluation.

On 15 May 1984, the United States Army Communications Command (USACC), a major command (MACOM) of the U.S. Army, was redesignated the United States Army Information Systems Command (USAISC). It was given the mission to manage the Information Mission Area (IMA), which was to place the responsibility for all areas of information management within the U.S. Army under one command. On the same date, the U.S. Army Computer Systems Command (USACSC), a field Operating Activity of the Headquarters, Department of the Army Assistant Deputy Chief of Staff for Operations-Command, Control, Communications, and Computers (C4), located at Fort Belvoir, Virginia, was transferred to the USAISC as a major subordinate command (MSC). Both of these actions were authorized by Department of the Army General Order No. 26, dated 25 July 84.

On 1 October 1984, the USACSC was redesignated the U.S. Army Information Systems Software Support Command (USAISSSC) by USAISC Permanent Orders 42-1, dated 14 September 84. Nine months later, the USAISSSC was redesignated the U.S. Army Information Systems Engineering Command (USAISEC) by USAISC Permanent Order 79-1, dated 1 July 85, and has retained this designation to the present day.

The U.S. Army Communication Systems Agency (USACSA) at Fort Monmouth, New Jersey, which had been established in 1967, was redesignated the U.S. Army Information Systems Management Agency (USAISMA) on 1 October 1984. On 1 July 1986, the USAISMA was merged with USAISEC and the combined organization retained the USAISEC name. The Commander of USAISMA became the Deputy Commander of USAISEC at the same time with duty station at Fort Monmouth. On 1 October 1987, the USAISEC Headquarters moved from Fort Belvoir, Virginia, to Fort Huachuca, Arizona, where it was collocated in Greely Hall with USAISC.

As a result of the changes associated with the Signal Organization and Mission Alignment (SOMA) process, USAISEC was realigned as a subordinate command of the U.S. Army Communications-Electronics Command (USACECOM) as of 1 October 1996. (USACECOM is a MSC of the U.S. Army Materiel Command (USAMC)).

Although USAISEC has undergone a great deal of turbulence during its history because of reorganizations and the move, it has continued to accomplish it's mission to provide the full spectrum of information systems engineering support to the entire U.S. Army. It's history may be short, but it's accomplishments are many and it has met the challenges all around the world for its supported customer organization.
