INTRODUCTION

Personnel turbulence and the lack of experienced personnel in militaryunits have often been cited as factors that creato training probltms (Dyer,Tremble & Finley, 1980; Funk, Johnson, Batzer, Gambell, Vandeoaveys, & Hiller,1980). Turnover disrupts training efforts and provides little continuity intraining personnel, so that new trainirg personnel at the squad, platoon, orcompany level cannot profit from the experience of their predeoesors. The useof inexperienced training personnel has a direct negetive impact upon trainingquality. Most Army training documents (e.g., FM 21-6, TC 21-5-7, TRADOC Cir-oular 351-8) fail to provide the type of Oetailed information needed •'n suchtraining situations. Only general guidanog is given regarding the manigementof personnel, resources and time during training periods, procedures ft,rpreparing, conducting and evaluating training, and forms of individual aindcollective training. Such documents do not address the more specificquestions of what objectives should be trained and what methods are best fortraining those specific objectives.

Some specific guidance regarding how to train within Infantry units isprovided, however, in ST 21-6-188-2. Training tips/aids and points to bechecked during company, platoon, and squad level ARTEP (Army Training andEvaluation Program) training missions are cited. Examples of training tips atthe squad level were "leader TEWT is useful to practice leader tasks," "varycombat power of thn force ony-cirn th'e souad from one man to one sound," and"use barrels, sandbags, old tires, and other rubble to simulate a bombed outcity." Yet none of these documents indicates what specific trainingproblems/needs are likely to occur, e.g., the mistakes that individuals arelikely to make in particular missions. The present study examined one way ofsystematically identifying such training problems/needs by capitalizing uponthe expertize of experienced training personnel.

An exploratory investigation was conducted to determine if individualswith Infantry company command experience could predict errors likely to bemade by Infantry squads in training situations. The particular situationexamined was an Infantry platoon in a MOUT (Military Operations in UrbanizedTerrain) training exercise. Although the results are limited in generality,they do provide some indication of the extent to which hoth individual andteam performance errors can be predicted, and of areas chat could beemphasized during squad training.

Previous analytic efforts In this area are meager. Military documents onMOUT (FM 90-10, ARTEP 7-15) provide little information on how to train forMOUT exercises and what to stress during those exercises. In an effort toimprove the training given by air crew commanders, Caviness and Titas (1977)recommended specific training procedures based on their experience as membersof alrorevs and as airorew instructors. Miraballa (1978) had noncommissionedofficers (NCOs) act at squad leaders and provide estimates regarding thespecific behavior of Infantry squads in ARTEP missions (e.g., maximum andminimum distances between fire teams, whether or not the enemy's observationpost would be detected prior to crossing a critical phase line, the likelihoodof the squad taking the observation post, time estimates for various missionphases, casualty 6stimates). The NCOs also made these predictions for fourhypothetical levels of squad training. Results indicated that the NCOs'estimates did distinguish among the training levels, but that the level ofagreement among the NCOs within each training level was low. The presentstudy did not require quantitative predictions like those obtained in theMirabella study, but was similar in that the estimates/predictions were basedupcn military experience.

METHOD

MOUT Training

An Infantry platoon consisting of two rifle sauads was observed duringMOUT training. The mission was to assault Pnd 3lear a two-story building.One squad assaulted the building, while the other squad provided supportingfire. During training the assault was rehearsed several times. A militaryexpert, a retired Infantry Lieutenant Colonel with particular expertise intraining, observed the assault and recorded errors made by the squad membcei-.These observations served as the criterion measures in the study.

Prediction of Squad Performance Errors

Five Infantrymen, two captains and three majors, each with previousInfantry company command experience, were asked to indicate the errors thatthe squad members were likely to make during MOUT training. These individualswere either in the Directorate of Combat Developments or the Directorate ofDoctrine and Literature within the U.S. Army Infantry School at Fort Benning.

The description of the MOUT mission given to each respcndent was asfollows:

To assault and clear a two-story building where the enemy may be located.The attack is to be conducted during daylight. The attacking forceconsists of two rifle squads--one to provide supporting fires while theother assaults the building.

Additional information regarding the MOOT setting was as folloas:

"The northeast corner of the building to be assaulted islocated approximately 100-200 meters from a woodline. Thebuilding is a wooden structure with windows and a highfoundation. A door is located at each end of the building.The woodline gradually curves away from the building on itseast side. About 20 meters to the west is another buildingwhich parallels the building to be assaulted. Other buildingsare located approximately 300-500 meters southeast and southwestof the building. In reality there is no enemy in the building.(See Figure 1 foi" a diagram of the MOUT setting).

The attacking force has no grapling hooks or rope. The squads arerelatively inexperienced with W3UT operations, obtaining moot of theirinformation via classroom lecture. They have had no previous fieldexperience with MOUT operations.

The respondents were asked to address three questions: (1) What errorsare likely to be made by the attacking squad when assaulting the building, (Z)what errors are likely to be made by the attacking squad when clearing thebuilding, and (3) what errors are likely to be made by the element providingsupporttve fire. The responses to these questions were then coded accordingto their agreement with the errors actually observed during training by themilitary expert. The codes were determined by the military expert and theauthor.

RESULTS

MOUT Training

One of the difficulties encountered by the squads was the absence of anopposing force. This made it difficult to evaluate the role of the supportingfire element, and for the assaulting squad to perform as it would if an enemywere actually present. To complicate this problem, little effort was made topresent a hypothetical enemy situation to the squads. The squads were notequipped with appropriate MOUT equipment, and they also had limited numbc•rs ofsimulators (smoke, grenades, etc.), Blank ammunition was provided to only themachine gunner, not the riflemen.

The squad attacked from the northeast, assaulted the northeast corner ofthe building, and entered the door on the north side (see Figure 2), Th..sapproach gave the squad the shortest route to the building, but it also meantttat they faced the higheet entry point into the building. The difficultentry slowed the entry process, and made the squad vulnerable to possibleenemy fire. The fire support element was in the woeds, at the looationindicated on the map (see Figure 2). This element did have good cover, as theground started to decline at the edge of the woodline. Only one machine gut.was available for the exercise.

* Prediction and Obsttrvation of MUT Errors

A summary of the responses made to the three questions is presented inTable 1. Of the 21 errors explicitly cited by the military expert, six ofthem were not predicted by any of the respondents, and only one error waspredicted by all five respondents (lack of coordination between the assaultand support elements (Table 7)). Most of the other errors were predicted byonly one or two of the respondents. Six other errors were predicted but wereMAX committed by the squads. A total of ten other errors were correctlypredicted, but were not explicitly cited by the subject matter expert. Ingeneral, most of the respondents' predictions were appropriate for the MOUTexercise, and most (71%) of the errors observed were predicted by at least oneof the respondents. However, there was relatively little overlap among therespondents' predictions.

Predictions regarding the assault phase of the MOUT exercise appeared tobe the most difficult to make. Responses to the assault question resulted inthe lowest degree of overlap among the respondents' predictions, the highestnumber of errors that were incorrectly predicted, and the highest number oferrors that were correctly predicted but were not explicitly cited by themilitary expert.

Tables 2, 4, and 6 present the predictions made by each of therespondents to each of the three questions. The errors observed by thl;military expert are presented in Tables 3, 9, and 7. The relationship betweenthe expert's observations and the respondents' predictions is also shown inthese tables.

The predictions made and the actual errors observed reflected bothin dtV-ual errors (,, 1-,A, rifl-e a-i,,g, exposure of body to open windows.and team errors. Team errors refer to squad behavior that lacked teamwnrk,that is, lack of coordination and planning among the individuals within thesquads, as wall as lacl" of coordination between the assault and supportelements. Examples of such errors were no communi1cation between downstairsand upstairs elements when clearing the building, lack of proper cover forindividuals clearing rooms by the remainder of the squad, and slow squadmovement from the woodline to the building.

DISCUSSION

Although the Investigation was restricted to a single training situation,was based on only one Infantry platoon, and had a limited number ofexperienced Infantrymen making predictions, the results indicate that theapproach har promise for future research efforts in the team training area.Obviously, tve staudv itrslf should be replicated, and more training situationsneed to be examined to determint the generalizatility of the findings. Twofindings are especially important in that they point to research designchanges that should be made ii future research dealing with such complex teamoperations as the Infantry squad MOUT mission. First, more than oneindividual should make predictions since there was little overlap among thesets of error predictions (e.g., only _9= error was predicted by everyone).Second, more than one expert is probably needed for observation as the expert

* in the present study did not formally record all of the errors he actuallyobserved. Other mehodological changes that might increase the agreementbetween the predicted and actual errors would be to use individuals to makepredictions who know the members of the units being trained and/or to reducethe free-response nature of the question*.

Before such diagnostic information can be used in the development ofinstructor guidebooks and training exercises, many additional questions needto be addressed. Such questions include can experienced training personnel atthe squad, platoon or company level predict the errors that will be the mostdifficult to correct, the errors that vary with the skill level or experienceof the individual and/or the squad, the training methods that are mosteffective in reducing such errors, and the best procedures for informinginexperienced leaders of such training problems.
