The Amphibious Reconnaissance Company (still under command of Capt. James Jones) was directed to report to the joint-Navy and Army's Amphibious Corps, Pacific Fleet (ACPF). The United States Navy controlled many joint units of the Army and the Marine Corps. These units represented the sum total of the amphibious forces of the United States, with the exception of small units of the Fleet Marine Force, which had been trained for amphibious raids.

. Soon after, each of the three rifle companies that were used during the Guadalcanal campaign were tasked in sending one their best field craft Marines to devise the scout-sniper unit, with each regiment containing a Scout and Sniper Platoon, within the regimental headquarters and service company.

Momentarily, the regiments requested their scouts to be heavily reinforced with tanks for rapid mobility and increased firepower, to allow their scouting parties to determine a hasty, yet accurate account of their enemies potential and strengths—using a technique known as reconnaissance-in-force  (RIF). RIF elicits determination of strength by offensively provoking the enemy for a reaction.

The close of World War II discontinued the use of amphibious reconnaissance, and momentarily the Amphibious Reconnaissance Battalion dismantled; all amphibious reconnaissance subsidiaries were under the direct control of the only-remaining division-level reconnaissance assets—ending force-level reconnaissance.

 units were formed to provided mechanized reconnaissance-in-force for infantry regiments. The responsibilities of the LAR battalions resemble those of the Scout (Tank)  companies of World War II.

It wasn't until the highlight of the Korean War that foresaw the re-establishment of force-level reconnaissance; however, only 2nd Amphibious Reconnaissance Battalion was created (1st Amphib Recon Bn remained inactive-only to be used as for training new amphibious reconnaissance candidates) in support of the Marine task force commanders' effort in pushing the Socialist Chinese forces north, from South Korea.

Deep operations

, and deception in the friendly forces' capabilities and intentions. In relation, reconnaissance operations support security operations by providing information on enemy forces, capabilities and intentions, and by denying the enemy information of friendly activities through counter-reconnaissance.

Through succession, security operations are usually integrated with its reconnaissance operations; in which force commanders acquire during offensive, defensive and other tactical operations. It greatly improves their decision-making process due to the collected information that is much needed to develop situational awareness and commander critical information requirements (CCIR).

The CCIR are designed to feed important, time-sensitive information to the commander so he can make a decision that should dramatically affect the battlespace

. The CCIR is collectively, a comprehensive list of high-prioritized information in which a force commander identifies as critical. It is much required to influence and facilitate timely information management and the decision-making process that may help dictate successful mission accomplishment. CCIR is divided into two key sub-components: "critical friendly force information" and "priority intelligence requirements".

Reconnaissance Planning

Reconnaissance supports the MAGTF commander’s intent and his CCIRs. While contributing to the commander’s broad situational awareness and development, reconnaissance assets tailor their efforts to support the specific CCIRs indicated by the commander’s intent and subsequent unit intelligence and operations planning. Simultaneously, reconnaissance forces must remain alert to any developments that may cause the commander to reassess that intent.

MAGTF reconnaissance assets are best employed early to support the CCIRs and friendly course of action development and selection. When reconnaissance is initiated early in the planning cycle, planning and execution are driven by the flow of solid, timely information and intelligence. If reconnaissance is delayed, situation development will generally be more uncertain. In this case, planning and execution can either take place in an information vacuum or be driven by the search for such information.

Reconnaissance assets are best employed in general support. Because of the nature of warfare, MAGTF reconnaissance units will most likely be employed in rapidly developing and fluid situations. The main effort may shift quickly from one subordinate element to another. Such situations often require modifications or complete changes in reconnaissance elements’ missions. The MAGTF commander and his staff are usually the most capable of determining the best use of MAGTF reconnaissance assets at any given time, to provide the necessary support, and to integrate the results of reconnaissance information with other intelligence sources. Although placing reconnaissance assets in direct support of some subordinate element or even attaching them to specific units is occasionally appropriate, in general, such support relationships make for inefficient use of specialized reconnaissance forces. Proper planning; the institution of flexible, responsive command and control and intelligence reporting procedures and networks; and clear intelligence reporting and dissemination priorities will ensure that the products of reconnaissance are shared to the maximum benefit of all potential users.

Reconnaissance requires adequate time for detailed planning and preparation. Most reconnaissance focuses on the enemy’s activities and intentions to satisfy the commander’s need to exploit the enemy’s vulnerabilities or to attack his center of gravity. This frequently necessitates operating in and around the enemy's most critical and best defended areas. This normally requires that reconnaissance be conducted over long distances and well in advance of commencement of the operations it will support. These conditions usually dictate specialized methods of transportation, communications and information systems support, combat service support, equipment, and coordination.

Remote Sensors and Imagery Interpretation

The intelligence battalion provides remote sensor, imagery interpretation, and geospatial [topographic] intelligence (GEOINT) support to MAGTF operations. In addition to the sensor control and management platoon (SCAMP), the force imagery interpretation unit, and the topographic platoon, the intelligence company establishes and mans the MAGTF’s surveillance and reconnaissance center. It plans, executes, and monitors MAGTF reconnaissance operations.

Counterintelligence and Human Intelligence

The intelligence battalion provides human intelligence (HUMINT), counterintelligence (CI), and interrogator-translator support to MAGTF operations. This support can include screening and interrogation/debriefing of prisoners of war and persons of intelligence interest; conduct of CI force protection source operations; conduct of CI surveys and investigations; preparation of CI estimates and plans; translation of documents; and limited exploitation of captured material. In addition to the specialized CI and interrogator-translator platoons, the company employs task-organized HUMINT Exploitation Teams (HET) in direct support of MAGTF subordinate elements. The HET combine CI specialists and interrogator-translators in one element, thereby providing a unique and comprehensive range of CI/HUMINT services.

Ground Combat Element

The Ground Combat Element (GCE) has substantial organic reconnaissance support assets. Any units in contact with the enemy, especially patrols, are among the most reliable sources of information.

Counterbattery Radar

Counterbattery Radar (CBR) platoons are located within the headquarters battery of the artillery regiment. The CBR Platoon's primary mission is to locate enemy rocket, mortar, and artillery weapons and process all acquired enemy locations in a timely manner for counter-fire and intelligence purposes. Secondary missions that can be assigned by the supported artillery unit are adjusting or registering artillery. They are normally employed as a unit and controlled by the regimental artillery commander. The CBR platoon commander coordinates the employment of radars operating under regimental control.

Light Armored Reconnaissance

The division Light Armored Reconnaissance battalions provides the Ground Combat Element with its light armored reconnaissance capability by operating in forward areas or along the flanks of Marine ground forces. Initially, they are usually used to provide early warning of contact by hostile forces, acting as the 'mechanized' reconnaissance-in-force, but they are capable of a wide variety of missions due to their inherent mobility and organic firepower; such as quick reaction force

Aviation Combat Element

The capability of the ACE to observe the battlefield and report in near-real time gives the MAGTF commander a multidimensional capability that should be used at every opportunity. Aviation combat units can view the entire AO in depth, providing early indications and warning and reconnaissance information that can be essential to the success of the MAGTF. Each ACE aircraft (rotary- or fixed-wing), can conduct visual observation of terrain and enemy forces that it may fly over. Given the combined arms capability of the MAGTF, these aircraft can engage enemy targets immediately or direct other supporting arms against the enemy forces. The ACE manages the following reconnaissance systems.

Unmanned Aerial Vehicles

UAVs provide day-night, real-time imagery reconnaissance, surveillance, and target acquisition. Its unique capabilities can also be used to support real-time target engagement, assisting in the control of fires/supporting arms and maneuver. The UAV provides high quality video imagery for artillery or naval gunfire adjustment, battle damage assessment, and reconnaissance over land or sea. It is capable of both day and night operations using TV or forward-looking infrared cameras. UAV squadrons are under the ADCON of the ACE. The MAGTF commander retains OPCON because of the limited number of UAV assets and the critical reconnaissance capabilities they provide to the entire force. Mission tasking is exercised through the surveillance and reconnaissance center.

Advanced Tactical Airborne Reconnaissance System

The F/A-18D can be equipped with the advanced tactical airborne reconnaissance system and the Radar Upgrade Phase II with synthetic aperture radar (SAR). The advanced tactical airborne reconnaissance system is a real-time digital package providing day/night, all-weather imagery capability. The imagery collected provides sufficient detail and accuracy to permit delivery of appropriate air and ground weapons, assist with battle damage assessment, and provide tactical commanders with detailed information about the enemy’s weapons, units, and disposition. Imagery resulting from collection can be digitally disseminated to the force imagery interpretation unit tactical exploitation group for exploitation, printing, and dissemination.

Electronic Reconnaissance and Warfare

Aerial electronic reconnaissance and electronic warfare is conducted using EA-6B aircraft. EA-6B aircraft also process and disseminate information from digital tape recordings obtained during electronic warfare missions to update and maintain enemy electronic order of battle information. The sensors are passive systems that require threat emitters to be active to collect.

Combat Service Support Element

As the CSSE is often in more direct contact with the indigenous population, it can collect HUMINT unavailable to the other MAGTF elements. For example, medical battalion personnel can often provide information on health conditions and their potential impact on operations. The CSSE is limited in its reconnaissance capabilities, having no dedicated reconnaissance capabilities. However, it can conduct road and route reconnaissance with its convoys, and military police.

The independent duty corpsmen (IDC) are assigned to the independently operated FMF Reconnaissance (Force Recon) companies, as the Special Amphibious Reconnaissance Corpsmen (SARCs).

National and Theater Assets

The MAGTF can draw on the full range of national, theater, joint, other service, and allied reconnaissance assets. When made available, these capabilities will be fully integrated into MAGTF reconnaissance operations; e.g., Joint Surveillance Target Attack Radar System (JSTARS), Navy SEALS or Army signals intelligence aircraft. During forcible entry operations, the MAGTF integrates its amphibious reconnaissance capabilities with national, theater, and special operating forces.

The Marine Corps component will support the MAGTF by monitoring the status of MAGTF reconnaissance requests to national and theater entities. The component coordinates the provision of Marine intelligence liaison to the joint task force and other component intelligence elements to satisfy the MAGTF’s requirements. Some MAGTF reconnaissance assets, such as the radio battalion and the CI/HUMINT company, will usually have direct connectivity with appropriate external agencies to coordinate tasking or support.
