c. The IMA operates in three environment:
the theater/tactical
environment, the sustaining base environment, and the strategic environment.
(1) The theater/tactical environment is generally described as an
operational army theater of operations.
The types of information systems
managed in this environment are those needed to direct coordination and
support combat, combat support, and combat service support forces in the
execution of their mission.
Examples of the information systems are the
Maneuver Control System (MCS), the Theater Army Medical Management
Information System (TAMMIS), and supporting communications systems such as
Mobile Subscriber Equipment (MSE). Geographically, this environment extends
from the tactical area of interest of the forward most deployed forces back
to the theater army rear boundary.
(2) The sustaining base environment encompasses the area located
outside of the area of operations. It encompasses the information resources
which have responsibility to raise, organize, train, equip, and deploy
forces in the accomplishment of their mission in the theater/tactical
environment.
Typical
information
systems
are
the
Standard
Installation/Division Personnel System (SIDPERS) and the Standard Financial
System (STANFINS). It is usually geographically located in the continental
United States (CONUS).
(3) The strategic environment does not exist in a true geographic
sense. It pertains specifically to the type of information systems required
to support decision making by the National Command Authority (NCA),
Secretary of Defense and Joint Chiefs of Staff (JCS) level of operation.
Typical strategic information systems are the Worldwide Military Command and
Control System (WWMCCS) and the Defense Communications System (DCS).
d. IMA Responsibilities
(1) HQDA. The Director of Information Systems for Command, Control,
Communications and Computers (DISC4) is the HQDA functional proponent for
the IMA and the management of information resources.
(2) MACOM.
The Deputy Chief of Staff for Information Management
(DCSIM) is the principal MACOM staff officer responsible for information
management. The commander or director of the U.S. Army Information Systems
Command (USAISC) activity in support of the MACOM is dual-hatted as the
MACOM DCSIM and assigned the responsibility for the IMA.
