Defense Primer: Intelligence Support to Military Operations


The statutory responsibility for resourcing and coordinating
the activities of the Intelligence Community (IC) in support
of military activities belongs to two senior executive branch
officials:

*  The Director of National Intelligence (DNI), who serves
   as the principal intelligence advisor to the President as
   commander   in chief (and in the President's other
   constitutional responsibilities), is responsible for
   national intelligence strategy, and the overall resourcing
   and coordination of intelligence activities across
   multiple agencies in support of the military's strategic,
   operational, and tactical priorities.

*  The Under  Secretary of Defense for Intelligence and
   Security (USD(I&S), using Under  Secretary of War for
   Intelligence and Security as a secondary title under
   Executive Order (E.O.) 14347, dated September 5,
   2025) is the senior-most Department of Defense (DOD,
   which is using a secondary Department of War
   designation, under E.O. 14347) official responsible for
   managing  the resources, capabilities, and activities of
   DOD   intelligence elements. This position is dual-hatted.
   When  acting as the USD(I&S), the incumbent reports
   directly to the Secretary of Defense (using Secretary of
   War  as a secondary title under E.O. 14347) and serves
   as the Secretary's principal staff assistant on
   intelligence, counterintelligence, security, and other
   intelligence-related matters. When acting as Director of
   Defense Intelligence (DDI), the incumbent reports
   directly to the DNI and serves as principal advisor on
   defense intelligence matters.

Many  of the 18 statutory intelligence elements, such as the
Central Intelligence Agency (CIA), directly support the
military. Nine of these reside within the Department of
Defense providing integrated intelligence support to
military strategy, planning, and operations. They include
the National Security Agency (NSA), National Geospatial-
Intelligence Agency (NGA), National Reconnaissance
Office (NRO), Defense Intelligence Agency (DIA) and the
intelligence components of the five military service (along
with the Coast Guard intelligence element when operating
as part of DOD).

The   Intellience Process for Supporting
Mihtary Operations
The IC supports the entire spectrum of DOD missions, from
peacetime to combat operations. Joint Publication 2-0, Joint
Intelligence, (or, JP 2-0, the Joint Chiefs of Staff
publication that provides definitive guidance on intelligence
support to military operations) notes that the intelligence
process for supporting joint (i.e., multi-service, integrated)
military operations consists of six interrelated categories of
intelligence operations, all aimed at providing to


commanders   and national-level decisionmakers relevant
and timely intelligence. These categories include planning
and direction; collection, processing and exploitation;
analysis and production; dissemination and integration; and
evaluation and feedback.

Intelligence professionals participate in the planning and
decisionmaking processes to align intelligence resources
with operational objectives. Collection managers ensure
collection resources support specific intelligence
requirements pertaining to operational objectives. Because
the operational environment is dynamic, the intelligence
process is iterative: each category or phase of the process is
ongoing and complements  the other phases for the duration
of the military campaign or operation.

koint  Intellience Roles and
Respons bihties
Table 1 summarizes  the roles and responsibilities of joint
intelligence to assist commanders in deciding which forces
to deploy; when, how, and where to deploy them; and how
to employ them in a manner that accomplishes a specific
mission consistent with the commander's priorities.

According to JP 2-0, intelligence should support a
commander's  planning, execution, and assessment of the
impact of military operations. It should, therefore, include a
comprehensive  analysis, under JP 2-0, of the threat and
relevant aspects of the operating environment in
assessments enabling the commander to create and exploit
opportunities to accomplish friendly force objectives.

In describing the operational environment, JP 2-0 specifies
that intelligence should describe the operational
environment for the commander, to include the political
context; governance; leadership intentions; military
capabilities and tactics; communications and critical
