This Directive applies to:

1. The Off ice of the Secretary of Defense (OSD), the Military
Departments, the Chairman of the Joint Chiefs of Staff and the Joint
Staff, the Unified and Specified Combatant Commands, the Inspector General
of the Department of Defense, the Defense Agencies, and the DoD Field
Activities (hereafter referred to collectively as "the DoD Components").

2. All new C3I systems (including nondevelopmental systems) and major
changes (e.g. release of a new software version) to existing systems that
must interact with or be integrated into the C3I structures of the
Department.

D. POLICY

It is DoD Policy:

1. That forces for joint and combined operations must be supported through
compatible, interoperable, and integrated C3I systems that can support
operations worldwide throughout the entire spectrum of conflict.

2. To establish as a long-term objective a DoD-wide, global C3I

3. In accordance with DoD Directive 5000.1 and DoD Instruction 5000.2
(references (b) and (c)), to develop, acquire, and deploy C3I systems and

compatible with existing and planned C3I systems, and other electronic
equipment, and that are interoperable with other U.S. and allied nations'
functionally related C3I information systems and equipment.  See 10 U.S.C.
2457 (reference (d)), which establishes a policy of Standardization and
interoperability within the North Atlantic Treaty Organization.

4. That, for purposes of compatibility, interoperability, and integration,
all C3I systems developed for use by U.S. forces are considered to be for
joint use.

5. That interoperability and integration of C3I requirements shall be
determined during the requirements validation process and shall be updated
as necessary throughout the acquisition period, deployment, and
operational life of a system.

requirements, make recommendations to the appropriate decision authority
about the conformance to the policies outlined in section D., above.

3. The Chairman of the Joint Chiefs of Staff shall:
