CORPS TASK ORGANIZATION AND
To make accurate decisions, commanders and staff officers must have a firm understanding of the capabilities, limitations, and employment considerations of organic and supporting friendly forces. Commanders and staffs can use the information in this appendix for preliminary planning. They can also use this information to understand and apply various corps assets to the battlefield. This appendix provides generic planning considerations by service and specialty.
Although situation-dependent, division (as well as separate brigade and ACR) commanders can expect to receive a portion of the corps' assets to accomplish their assigned missions. A commander of a committed division may receive the following additional support depending on METT-T factors:
- Additional maneuver units (an ACR, a separate brigade, an AH battalion, or a ground maneuver brigade from another division within the corps).
- Air defense artillery assets (an ADA battalion or ADA batteries of guns and/or short-range missiles).
- Chemical assets.
- Engineer assets (an engineer battalion or an engineer group with attached engineer battalions or companies and a bridge company).
- Field artillery assets (an FA brigade with an appropriate mix of FA units).
- Military intelligence assets.
- Military police assets (an MP company).
- Psychological operations assets.
- Signal assets as required to support task organization (a node center or extension switch).
- Civil affairs assets (a CA battalion with both financial specialists and generalists).
- Corps support command assets as required to support task organization, including the following corps support depending on METT-T factors:
- A DS maintenance company.
- Missile maintenance support.
- Aircraft maintenance support.
- A surgical team.
- An air ambulance.
- Mortuary affairs.
- Ammunition support.
- Port/airfield clearance.
- A field services company.
- Other combat support (a command aviation company of the corps aviation brigade) and CSS assets (a transportation company) as required.
- Close air support allocation and priority of effort (time, location, target type, or situational considerations).
- Priority of corps GS assets.
- Naval surface fire support and ANGLICO assistance.
A commander of an uncommitted division may receive, with the exception of FA, MP, and CAS allocations, the same type of corps augmentation, although allocated units may be smaller. When a previously uncommitted division becomes committed, the corps organization for combat, or a revised or phased task organization, will redistribute the available corps assets and priorities to support mission accomplishment by the division. The command and support relationships of assets allocated to either committed or uncommitted divisions depend on the situation and are designed to meet the specific missions of the division.
- Determines how and where to use combat air capabilities.
- Joint force commander assigns a percentage or priority of combat air effort to the various air operations (AI, counter air, CAS).
- Air reconnaissance is generally not apportioned.
- Translates the JFC's apportionment decision into sortie numbers (by type aircraft) available for each operation or task.
- Is the responsibility of the ACC.
Distribution of CAS among the subordinate land maneuver units is conducted by the LCC .
- Is the responsibility of the ACC and must meet the JFC's apportionment and intent.
- Is used in NATO to assign individual aircraft to combined air operations centers (CAOCs) to carry out JFC objectives.
- Is usually accomplished by entire squadrons assigned for a specific period of time (for example 24 hours) or for a particular mission (such as a deep strike).
- Objective is to gain control of the aerospace environment to achieve air supremacy.
- Operations protect friendly forces, ensure freedom to perform other missions, and deny that freedom of use to the enemy.
- Is conducted in a manner or at a distance to render unnecessary detailed integration with fires and the movement of friendly ground forces.
- Is consistent with the JFC's objectives, and may initially involve the highest priority of all air operations.
- Performs offensive, defensive, and SEAD operations.
- Air component commander determines ratio of forces assigned between counter air operations based on--
- JFC guidance.
- Level of enemy air threat.
- Vulnerability of friendly forces to air attack.

- Command and control facilities.
- Munitions and missile storage sites.
- Aircraft on the ground or in the air.
- Any target that contributes to the enemy's air power capability.
Defensive Counter Air (DCA)--
- Operations detect, identify, intercept, and destroy enemy air power attempting to attack friendly forces or penetrate friendly airspace.
- Initially may be the mission of emphasis if the enemy has seized the initiative through surprise or friendly political constraints.
- Involves active measures such as using combat fighter aircraft and air defense artillery.
- Involves passive measures, such as--
- Not involving weapons systems.

- Protective construction (for example, hardened sites).
- Cover, camouflage, deception, dispersion, and frequent movement of personnel and equipment.
Suppression of Enemy Air Defenses (SEAD)--
- Operations neutralize, destroy, or temporarily degrade enemy AD systems.
- Goal is to allow friendly aviation forces to effectively perform other missions without interference from enemy air defense.
Joint Suppression of Enemy Air Defenses (J-SEAD)--
- May be part of SEAD operations; land force surface-to-surface weapons will complement these efforts.
- Is conducted by the ACC at the theater level against surface-to-air defense systems.
- Are planned and conducted in localized areas by battalion and larger land units to protect aviation and friendly aircraft; localized J-SEAD operations can use FA, attack helicopters, direct fire weapons, and EW.
Air Interdiction (AI)--
- Delays, disrupts, or destroys the enemy's potential before he can use it effectively against friendly forces.
- Reduce the enemy's capability to mount an offensive.
- Restrict the enemy's freedom of action and increase vulnerability to friendly attack.
- Prevent the enemy from countering an increase in friendly strength.
- Reduce the enemy's battlefield reserves.
- Attacks are normally executed by the ACC as part of a systematic and persistent campaign in support of the JFC's strategy.
- Includes actions against land force targets nominated by the LCC or the Army corps, which are in a position to have a near-term effect on the corps battle but are not yet in close proximity to ground forces.
- Targets are nominated by corps commanders and are prioritized according to nominations of all corps/service components in theater and the JFC's objectives.
- Requires joint coordination during planning.
Close Air Support (CAS)--
- Are attacks against hostile surface forces that are in close proximity to friendly forces and which require detailed integration into the supported commander's scheme of fire and maneuver.
- To be successful, must be responsive to the ground commander's needs.

- Is conducted--
- To blunt an enemy attack on a friendly position.
- To help obtain and maintain the land offensive.
- To provide cover for friendly movements.
- Targets are selected by the ground commander.
- Is planned, directed, and controlled by elements of the theater air control system.
Reconnaissance and Surveillance--
- Objectives are to collect information from airborne, orbital, and surface-based sensors to identify the enemy's composition, capability, and intent.
- S2/G2 normally handles preplanned requests for aerial reconnaissance; the appropriate TACP handles immediate requests.
- Objectives are to deploy, employ, and sustain military forces by the timely movement, delivery, and recovery of personnel and equipment.
- Through mobility operations, allows the JFC to maneuver fighting forces to exploit an enemy's weakness.
- May be categorized as either strategic or theater; corps requests--
- For strategic airlift are handled through TRANSCOM channels.
- For theater airlift are handled through Army logistic channels, with variations for the immediacy of the request.
- For when movements are known or projected in advance, are handled as planned requests through normal logistic channels as part of the JMC's daily airlift allocation.
- For when air movement requirements are identified too late for normal coordination, are handled as immediate.
- Once identified by the Army, are transmitted directly to the AOC, normally by a TALO.
- Is a procedural method to separate fixed-wing and rotary-wing aircraft.
- Is determined by the theater airspace control authority (ACA).
- Normally extends from the corps rear boundary to the FLOT.
- May extend forward of the FLOT.
Airspace Restricted Area--
- Is also known as the restricted operations area (ROA) and/or restricted operations zone (ROZ).
- Is normally activated for DZs, ADA weapons-free zones; and so on.
- Requests are sent through A2C2 facilities to the ACA.
Minimum-Risk Route (MRR)--
- At NATO is known as the low-level transit route (LLTR).
- Represents minimum hazard to friendly USAF aircraft transiting a specific area.
- Is recommended by the corps and sent through the LCC to the ACA.
- Normally begins at the corps rear boundary and ends at the FSCL.
- Should be changed frequently to prevent enemy exploitation.
- May extend below the coordinating altitude to increase aircraft survivability.
- Should be active in the corps at any onetime with several inactive alternates.
- Must avoid areas where intense ground combat is projected and where there will be areas of high airspace use, such as--
- Field artillery areas.
- Air defense areas.
- Drop zones.
- Army aviation operations areas.
High-Density Airspace Control Zone (HIDACZ)--
- Is requested by the maneuver force commander (division or higher).

- A ship in direct support (normally to a battalion) delivers both planned and call-fire missions.
- Call-fires are requested and adjusted by a shore fire control party of the supported unit or by an air spotter.
- General support; for example--
- Is assigned to ships supporting units of brigade size or larger.
- Normally has an air observer who adjusts the fires of a GS ship or it has an LNO who assigns the fires of the ship to a battalion shore fire control party.
- Selection of the most favorable gun-target line within the limits imposed by hydrography.
- High rates of fire.
- A variety of weapons and munitions.
- High initial velocity and flat trajectory for direct fire against fortifications.
- Ship/shore communications dependent on radio transmission.
- Changing gun-target lines when the ship is under way.
- Inaccuracies in unobserved fires and initial salvos in areas where navigational aids are lacking or obscured by poor visibility (employing radar beacons ashore can minimize this).
- Limited magazine capacity of fire support ships.
- Firing positions possibly limited by unfavorable hydrographic conditions or the presence of mines.
- Flat trajectories that are relatively unsuitable for the attack of targets in defiladed positions and that restrict the attack of targets close to front-line troops when the gun-target line passes over friendly troops.
- The fact that the dispersion pattern of the naval gun is elliptical with-the long axis of the pattern along the direction of fire; however, this pattern--
- Can be particularly effective when fire can be brought to bear on the long axis of an enemy target.
- Allows fire to be brought close to friendly front lines when the gun-target line parallels those lines.

The largest portion of USMC operating forces are located within fleet marine forces. They are integral parts of the US fleets and are subject to the respective fleet commanders' OPCON.
There are three types of organizations within each FMF: Marine divisions (MARDIVs), Marine aircraft wings (MAW), and force service support groups (FSSG). Elements of the FMFs are task-organized into Marine air-ground task forces (MAGTFs) for combat operations.
Marine Air-Ground Task Forces (MAGTFs)--
- Are combined-arms forces, under the direction and control of a single commander, consisting of ground, air, and CSS elements capable of operating as independent units or as part of a joint or combined task force.
- Include four major elements:
1. A command element (CE) that provides a single headquarters for command and coordination of ground, air, and CSS forces.
2. A ground combat element (GCE) taskorganized to conduct ground operations and constructed around an infantry unit varying in size from a reinforced infantry battalion to a reinforced MARDIV.
3. An aviation combat element (ACE) task-organized to provide all or a portion of the fictions of USMC aviation (normally one per MAGTF).
4. A combat service support element (CSSE) task-organized to provide the MAGTF with the logistic support necessary to accomplish the MAGTF mission.
The CEs of all the MAGTFs are always staffed. The MAGTFs are only "fleshed out" with a GCE, an ACE, and a CSSE for a specific deployment, exercise, or contingency.
There are three basic types of MAGTFs--the Marine expeditionary unit (MEU), the Marine expeditionary brigade (MEB), and the Marine expeditionary force (MEF). Command elements have been established for 6 MEUs, 6 MEBs, and 3 MEFs. The MAGTFs are task-organized according to the following operational requirements:
- The Marine expeditionary unit (MEU) (Figure A-2)--
- Which is the most responsive but has the least combat power of all MAGTFs.
- Which, while normally sea-based aboard from three to five Navy amphibious ships, may be airlifted.

- An ACE consisting of a helicopter squadron (reinforced) containing four types of rotary-wing aircraft and fixed-winged vertical short takeoff/landing (VSTOL) aircraft/Avenger (AV) 8-B.
- A CSSE, which can provide 15 days of CSS before requiring resupply.
- The Marine expeditionary brigade (MEB) (Figure A-3)--
- Capable of forward-deploying aboard naval amphibious ships but which will normally be found forward-deployed ashore.
- Requires from 26 to 32 USN amphibious ships to deploy.
- May be airlifted.
- Has more combat power than a MEU.
- Currently transitioning to a MEF (forward) stucture.
- Is composed of--
- Approximately 16,000 personnel.
- ACE commanded by a brigadier general.
- A GCE regimental landing team (RLT) consisting of an infantry regiment, reinforced by an artillery battalion, tank company, combat engineer company, reconnaissance company, assault amphibian vehicle company, light armored vehicle company, and TOW platoon.
- An ACE consisting of a Marine aircraft group (MAG) (reinforced) containing fixed- and rotary-wing aircraft; command, control, and air defense elements; and an air field support detachment.
A CSSE capable of providing 30 days combat support to a MEB before resupply is required.
- The Marine expeditionary force (MEF) (Figure A-4)--
- Is the largest and most combat capable of the three MAGTFs.
- Is capable of a broad spectrum of amphibious operations and subsequent operations ashore.
- Takes from 60 to 70 USN amphibious ships to deploy a MEF.
- May be forward-deployed aboard naval amphibious ships but will normally be found forward-deployed ashore.
- Is composed of--
- Approximately 53,000 personnel.
- A CE commanded by a major general or lieutenant general.
- A GCE that is normally a MARDIV (reinforced).
- An ACE consisting of a task-organized MAW that may include elements of other aircraft wings for additional combat power.
- A CSSE that is normally an FSSG or FSSG (reinforced) and that provides up to 60 days logistic support before resupply is required.
