Any plan, except for the Single Integrated Operational Plan, for the conduct
of military operations. Plans are prepared by
combatant commanders in response to requirements established by the Chairman
of the Joint Chiefs of Staff and by commanders of subordinate commands in
response to requirements tasked by the establishing unified commander.
Operation plans are prepared in either a complete format (OPLAN) or as a
concept plan (CONPLAN) The CONPLAN can be published
with or without a time‑phased force and deployment data (TPFDD) file.
a. OPLAN—An operation plan for
the conduct of joint operations that can be used as
a basis for development of an operation
order (OPORD) An OPLAN identifies the forces and supplies required
to execute the CINC's Strategic Concept and a movement schedule of these
resources to the theater of operations. The forces and supplies are identified in TPFDD files. OPLANs will include all
phases of the tasked operation. The plan is prepared with the appropriate
annexes, appendixes, and TPFDD files as described in the Joint Operation
Planning and Execution System manuals containing planning policies, procedures,
and formats. b. CONPLAN—An operation plan in an abbreviated format that would
require considerable expansion or alteration to convert it into an OPLAN or
OPORD. A CONPLAN contains the CINC's Strategic Concept and those annexes and
appendixes deemed necessary by the combatant commander to complete planning.
Generally, detailed support requirements are not calculated and TPFDD files
are not prepared. c. CONPLAN with
TPFDD—A CONPLAN with TPFDD is the same as a CONPLAN except that it
requires more detailed planning for phased deployment of forces (Army) Any
plan for the preparation, execution, and assessment of military operations.

translates the joint force commander's strategy into operational design, and,
ultimately, tactical action, by integrating the key activities at all levels
of war, also strategic level of war; tactical level of war, FM 3‑0) operational command (NATO)
The authority granted to a commander to assign missions or tasks to
subordinate commanders, to deploy units, to reassign forces, and to retain or
delegate operational and/or tactical control as the commander deems
necessary. Note: It does not of itself include responsibility for
administration. [Note: this term is only used within
the context of NATO operations.] Also called OPCOM, also operational
control, FM 100‑8) operational
control (DOD) Command authority
that may be exercised by commanders at any echelon at or below the level of
combatant command. Operational control is inherent in combatant command
(command authority) and may be delegated within the
command. When forces are transferred between combatant commands, the command
relationship the gaining commander will exercise (and the losing commander
will relinquish) over these forces must be specified by the Secretary of
Defense. Operational control is the authority to perform those functions of
command over subordinate forces involving organizing and employing commands
and forces, assigning tasks, designating objectives, and giving authoritative
direction necessary to accomplish the mission. Operational control includes
authoritative direction over all aspects of military operations and joint
training necessary to accomplish the missions assigned to the command.
Operational control should be exercised through the
commanders of subordinate organizations. Normally this authority is exercised through subordinate joint force commanders
and Service and/or functional component commanders. Operational control
normally provides full authority to organize commands and forces and to
employ those forces as the commander in operational control considers
necessary to accomplish assigned missions; it does not, in and of itself,
include authoritative direction for logistics or matters of administration,
discipline, internal organization, or unit training. Also called OPCON, also assign; combatant
command; combatant command
(command authority);
detachment; operational command; tactical control, FM 3‑0) operational decontamination (DOD,
NATO) Decontamination carried out by an individual and/or a unit, restricted
to specific parts of operationally essential equipment, materiel, and/or
working areas, in order to minimize contact and transfer hazards and to
sustain operations. This may include decontamination of the individual beyond
the scope of immediate decontamination, as well as decontamination of mission‑essential
spares and limited terrain decontamination, also decontamination;
immediate decontamination;
thorough decontamination, FM 3‑5) operational environment (DOD)
A composite of the conditions, circumstances, and influences which affect the
employment of military forces and bear on the decisions of the unit
commander. Some examples are as follows: a. permissive environment—Operational environment in which host
country military and law enforcement agencies have control as well as the
intent and capability to assist operations that a unit intends to conduct. b.
uncertain environment—Operational
environment in which host government forces, whether opposed or receptive to
operations that a unit intends to conduct, do not have totally effective
control of the territory and population in the intended operational area. c. hostile environment—Operational
environment in which hostile forces have control and the intent and capability
to effectively oppose or react to the operations a unit intends to conduct, FM 3‑07) operational fires The
operational‑level commander's application of nonlethal and lethal
weapons effects to accomplish objectives during the conduct of a campaign or
major operation (FM 3‑0) operational

battlefield organization;
battlespace (FM 3‑0) operational level of war (DOD)
The level of war at which campaigns and major operations are planned,
conducted, and sustained to accomplish strategic objectives within theaters
or operational areas. Activities at this level link tactics
and strategy by establishing operational objectives needed to accomplish the
strategic objectives, sequencing events to achieve the operational
objectives, initiating actions, and applying resources to bring about and
sustain these events. These activities imply a broader dimension of time or
space than do tactics; they ensure the logistic and
administrative support of tactical forces, and provide the means by which
tactical successes are exploited to achieve strategic objectives, also strategic level of war; tactical level of war, FM 3‑0) operational
military deception (DOD) Military deception planned and
executed by and in support of operational‑level commanders to result in
adversary actions that are favorable to the originator's objectives and

together to derive critical information in time to be useful to adversaries;
and c. select and execute measures that eliminate or reduce to an acceptable
level the vulnerabilities of friendly actions to adversary exploitation. [Note: the Army replaces "critical
information" with "essential elements of friendly
information."] Also called OPSEC,
