Besides having some of the most com­plex terrain with the most variable weather conditions at any of the CTCs, JMRC has the unique opportunity to routinely train with Infantry, Mobile, Stryker, Armor, and Mul­tinational Bri­gades. As the new Army Struc­ture (ARSTRUC) is imple­mented across the force with multiple func­tional and organi­zational changes for all formations, consistent trends in re­connaissance and security challenges are evident. Understand­ing reconnaissance and security as tasks that enable specific purposes for the brigade combat team (BCT) re­mains critical and has only gotten more challenging as we integrate new tech­nology into our own force while in con­tact with near peer capabilities. The tools are changing, but the fundamen­tals of reconnaissance and security re­main reliable guideposts for planning, resourcing, and executing these critical tasks. The institutional Army – particu­larly the Maneuver Center of Excellence – and our CTCs remain the premier venues to adapt to these changes and train the force on recon­naissance and security.

Death, Taxes, and R&S Are Eternal

The Battle of Arracourt, fought in Sep­tember 1944 between the US Army’s 4th Infantry Division and the German 5th Panzer Army, highlighted the criti­cal importance of ground reconnais­sance particularly when conditions were not ideal for collection via aerial means. During the battle, environmental conditions consisting of dense fog and poor weather limited American aircraft from providing aeri­al reconnaissance and close air sup­port necessitating the commander’s reliance on ground-based reconnais­sance assets to track German for­mations. Despite adverse weather conditions and visibility, these ground-based as­sets provided timely and accu­rate intelligence allowing US forces to set up a well-coordi­nated defensive position. The Americans de­stroyed dozens of German tanks and halted their of­fensive, resulting in a de­cisive American victory.

In 2016, after the reflagging of the Ar­my’s last Armored Cavalry Regiment in 2011, US Army Forces Command (FORSCOM) directed the 1st Stryker brigade combat team (SBCT), 4th In­fantry Division to conduct a study to determine the feasibility of a SBCT ef­fectively conducting reconnaissance and security (R&S) tasks in support of a Division or Corps. Although this study was conducted at a higher ech­elon, a key finding resonates in the post-ARSTRUC era:

“Perhaps the most important lesson we learned is the tradecraft of R&S is difficult to master for both the individual and the organization. True expertise requires a career of focused study and attention. The complexity of R&S missions only increases as one moves from platoon up through the echelons to BCT-level operations. The achievement and preserva­tion of mastery takes generations to build and can be lost in a decade or less. Regardless of the organizational design the Army ultimately decides, it is our position that the Army should maintain at least one or more brigade-sized com­bat formations with the primary mission to fight for information. We cannot wait to build this expertise after a crisis arises.”

This article is not a call for the return of the Cavalry Squadron. We as a force have acknowledged the need for a leaner Army; however, the require­ment to conduct R&S still exists. The advent of new and more sophisticated tools such as unmanned aerial systems (UAS), unmanned ground vehicles (UGV), enhanced electronic warfare (EW), extended lethality, and artificial intelligence enhanced mission com­mand systems all make the BCT expo­nentially faster, more lethal, and more survivable. But only if BCTs apply new tools appropriately to deliver recon­naissance and security for the forma­tion to enable the main effort and ac­complish the mission.

The Fundamentals are Fundamental

According to FM 3-98 “recon­naissance is a mission to obtain, by visual observation or other detection methods, information about the activities and resourc­es of an enemy or adversary, or to secure data concerning the… characteristics of a particular area.” Whether pushing, pulling, mounted, dismounted, conduct­ing aerial, or recon by fire recon­naissance, the fundamentals of reconnaissance have guided the basic employment of forces to obtain information critical to mission success.

Crucial to employment of these funda­mentals is the basic elements of com­mand reconnaissance guidance. Com­manders – at a minimum – must artic­ulate reconnaissance focus, tempo of reconnaissance, engagement/disen­gagement criteria, and displacement criteria to drive reconnaissance suc­cess.

According to ADP 3-90, security is a distinct and separate requirement for a BCT, where “the main difference be­tween conducting security operations and reconnaissance is that security op­erations orient on the force or facility being protected while reconnaissance orients on the enemy and terrain.” The tactical tasks of screen, guard, and cov­er are often loosely used to describe a mission requirement to orient on the protected entity to provide space, time, and early warning to al­low the commander to achieve the primary end state desired. Once again, our fundamentals have reliably guided the em­ployment of forces to achieve a security end state that enable the main effort.

Observations from all the CTCs consistently highlight challeng­es in providing clear command guidance to enable effective R&S operations; timely military decision making process (MDMP) that allows R&S forces sufficient space and time to achieve commander’s intent; a lack of a synchronized or inte­grated information collection plan to enable mixing and cueing of ca­pabilities; and insufficient resources applied to solve the tactical problem presented. So what’s new that’s worth mentioning?

Those previous observations were en­during with each BCT formation arriv­ing at a CTC with a purpose built orga­nization trained specifically in R&S tasks. With the implementation of the ARSTRUC, JMRC observer controller/ trainer (OC/Ts) are seeing these same trends defined in new ways. BCTs con­tinue to struggle with the most com­monly observed trends but that strug­gle is compounded by new challenges. BCTs now have a knowledge gap in the formation, are hard-pressed to allocate sufficient combat power to achieve de­sired R&S outcomes, all while having too many new technological tools that can do too many things.

Emerging Trends: Someone Has To Do R&S

As BCTs fully reorganize in accordance with the ARSTRUC a knowledge gap is emerging that challenges formations to effectively develop the battlefield. BCTs continue to execute effective in­telligence preparation of the opera­tional environment (IPOE) to provide a detailed evaluation of the threat and terrain. Visualization tools are allowing BCTs to build more sophisticated ene­my event templates that visualize the enemy in space, time, and terrain.

These tools should drive effective in­formation collection planning as units exit mission analysis and continue to­wards course of action development. The information collection synchroni­zation matrix (ICSM) is the key warf­ighting product that synchronizes col­lection assets in time and space against both priority and target intelligence re­quirements and should be a key output of mission analysis. But too often the ICSM does not account for the limita­tions of new forms of reconnaissance and security. For example, ICSMs con­sistently reflect medium and long range reconnaissance unmanned aeri­al system (UAS) as 24/7 all-weather sensors. All systems observed at JMRC have limitations dictated by the com­plex terrain and often punishing weather conditions that inhibit adver­tised performance. For example, tem­peratures dropping below zero re­duced the battery performance to less than 67% of the Motorized Rifle Regi­ment (MRR) platform’s advertised ca­pability during rotations in the winter. Finally, operator fatigue, coupled with rest and security plan requirements, prevents units from executing their planned collection. In lieu of 24/7, all-weather assets, the brigade informa­tion collection (IC) manager must com­pletely understand asset capabilities and deliberately schedule their use over named areas of interest (NAIs) to meet the priority intelligence require­ments.

Further complicating R&S planning is the multitude of things UAS and other capabilities can do but cannot do all at once. Developing the situation, con­firming or denying the enemy most likely versus most dangerous, develop­ing targets, and assessing effects are all essential tasks. But UAS are limited in number, flight time, and field of view. They cannot do all these things at once or even in close sequence. UAS operators and collection managers must maintain a clear understanding of what is the most important require­ment at any given time and remain dis­ciplined in employment of assets. This does not mean strict obedience to the plan, but it does mean a full under­standing and adherence to the com­mander’s intent as outlined in the re­connaissance or security guidance.

Without a dedicated ground R&S unit, a detailed IC plan is essential to pro­vide situational understanding and tar­geting. The reorganized BCTs must ex­ecute routine assessments of IC after each key event on the event template to determine the performance and ef­fectiveness of assets in collecting pri­ority intelligence requirements (PIR) while identifying areas for improve­ment. These assessments should be completed by the brigade R&S cell, which should flatten the planning con­siderations of fires, information collec­tion, and reconnaissance/security. The brigade R&S cell should oversee these assessments and feed into the contin­uous updating of IPOE, the IC plan, and the brigade’s targeting cycle. ABCTs are part of this dialogue as well – the in­corporation of UAS, EW, and UGVs in the armor formation presents new challenges in maintaining tempo even with the retention of the cavalry squadron.

The information collection plan out­lined in Annex L is the foundational product that drives the scheme of ma­neuver of any unit tasked with R&S. As an enabling task executed on behalf of the brigade, the R&S unit’s planner, S3, and/or commander should integrate into the brigade’s planning process, greatly facilitating parallel planning at the battalion level. As a best practice, the brigade commander and R&S unit commander conduct an R&S huddle as part of the mission analysis process. The R&S huddle is the initial dialogue between commanders to develop com­mander’s reconnaissance and security guidance, proposed commander’s crit­ical information requirements (CCIRs), identification of R&S objectives, and addition of battalion assets to the bri­gade information collection plan. Key to successful R&S operations is a syn­chronized plan that meets brigade re­quirements, not a stand-alone battal­ion R&S plan independent of the bri­gade’s plan.

It is imperative that the commander’s R&S guidance from this huddle be pub­lished in the brigade’s warning order (WARNORD) #2 under the execution paragraph. This will allow battalion planners to stay within the command­er’s visualization for the reconnaissance and security mission. This will ensure that the light brigade combat team (LBCT) R&S unit collect and report only the most important in­formation in a timely and effective manner.

Multi-Functional or Multi-Purpose Reconnaissance Best Practices

The US Army has intentionally not de­fined the task and purpose of the new multi-purpose company, leaving bri­gade’s ability to develop their own doc­trinal templates (DOCTEMP) on their employment that will eventually in­form future doctrine. Mobile and Stryker brigade combat teams contin­ue to experiment with a mix of organi­zations and technologies to fill the gap left with the loss of cavalry squadrons. A decrement of TOW/ITAS and Javelins with the deletion of the cavalry squad­rons plus the loss of the weapons com­panies challenges BCTs’ ability to apply lethality forward to establish effective security or fight for information.

Multi-function organizations that com­bine UAS, Low Altitude Stalking and Strike Ordnance (LASSO), EW, mortars, and traditional scout platoons at the brigade and battalion level offer capa­bility that answer some of the funda­mental R&S challenges that must be addressed, but their purpose remains vague. Are they R&S elements? Are they more aligned to the fires war fighting function, focused on the “bat­talion and brigade deep fight? Do they focus on supporting companies in the close fight? Do they develop targets as part of the kill web? The answer is probably – all of the above.

The multi-function concept is intended to provide a flexible and adaptable force that can perform a variety of tasks, including reconnaissance, secu­rity, and targeting while also support­ing the maneuver of the rifle compa­nies. Gaps in the doctrine, organiza­tion, training, materiel, leadership and education, policy, facilities (DOTMLPF) framework and implementation of this multi-functionality leads to brigades interpreting their employment in their own way. However these organizations are employed, the key to the unit’s success will be the early integration of the multi-functional unit commanders into the higher headquarters’ MDMP as the executor of the battal­ion and brigade’s tactical en­abling tasks. Commanders at echelon must still provide re­connaissance and security guidance, employment of IC assets in time and space, de­termine priorities of fires, the high payoff target list, the at­tack guidance matrix, and tar­get selection standards. Sub­ordinate multi-functional commanders must understand how to employ their capabili­ties within the framework of these products to enable the ground tactical plan.

Where to Go From Here?

The great news as the Army continues to transform is that our R&S fundamentals are still sound principles to guide

planning and execution, re­gardless of the new tools and organi­zations we are developing. The Maneu­ver Center of Excellence (MCOE) has some of the answers. The Cavalry Leader Course (CLC), Scout Leader Course (SLC), and Reconnaissance and Surveillance Leader Course (RSLC) are all grounded in the fundamentals. As new tactics, techniques, and proce­dures emerge we must continue to up­date our programs of instruction to provide the premier institutional edu­cation the force needs to solve old R&S problems with new tools.

All brigades must take advantage of that learning opportunity. Talent man­agement is more important than ever to thoughtfully develop the key skills, knowledge, and attributes for key lead­ers in multi-functional organizations. Brigade commanders will ask these or­ganizations to help solve the R&S prob­lem at echelon – they must train them accordingly. Plan ahead to send and graduate the right leaders from key schools to lead new capability. If bri­gades want leaders who can leverage multi-functional capability to establish security or conduct reconnaissance, they better ensure those leaders un­derstand the fundamentals. The tools are changing, but the fundamentals still work as a heuristic to understand planning and execution towards an end state.

As a profession we must continue to have flat and honest dialogue to share best – and worst – practices as we transform. The strength of our profes­sion and our Army is our ability to learn through effective after action re­views and professional dialogue. Every brigade is rapidly learning. Flat com­munications and brutal honesty ensure we don’t learn the same things over and over.

Last but not least, our combat training centers continue to be the Army’s learning laboratory. All the CTCs are modernizing and transforming along with the Army to remain the premier locations to bring new ideas and meth­ods to test in simulated combat. Our opposing force (OPFOR) remain devi­ous, innovating at the same pace as our BCTs to provide the most realistic near-peer threat to challenge units to the brink of failure. We all remain the

U.S. Army’s first battlefield for the force, where Soldiers and leaders can come sweat and cry in their first battle so they don’t bleed and die in their second.
