SKIRMISH AND AMBUSH--TACTICAL BOARD GAMES

FOR DEVELOPMENT AND EVALUATION

OF ROAD TRANSIT PHYSICAL PROTECTION SYSTEMS

Introduction A principle objective of the Nuclear Regulatory Commission (NRC) is to protect the public from any misuse of the nuclear energy fuel cycle. Part of satisfying this objective is the establishment of appropriate safeguards for the nuclear industry. To this end, one NRC program l is establishing improved methods of protecting special nuclear material (SNM). As part of this NRC program, Sandia Laboratories, Livermore, CA (SLL), developed several methods for evaluating transportation protection schemes. To complement computer simu­ lation models 2- 9 , Sandia has developed two related tactical board games-­ SKIRMISH and AMBUSH--designed to simulate the attempted theft of SNM from truck convoys. Board games can give valuable insight into combat situations since each player must make all decisions regarding the deployment and tactics of the units under his command. To computerize this degree of player involve­ ment would require development of an interactive graphic model, an expensive and time-consuming task with an end product which is difficult to share. The major difference between the two games is the level of complexity, with SKIRMISH being the simpler, introductory version. Development of SKIRMISH is complete, and the rules are contained in this report together with all the information to construct a copy of the game. Test copies of SKIRMISH were dis­ tributed to a diverse group of potential users, which included representatives from the NRC, Sandia Laboratories, Livermore and Albuquerque, DOE, the US Army Special Forces, Tri-State Motor Transit Company, and Missouri Southern State College. The feedback received was considered when the final version of the game was prepared. AMBUSH contains additional features not found in SKIRMISH. As such, it represents a more comprehensive simulation of battle conditions but is considerably more complex. The differences between SKIRMISH and AMBUSH have been outlined previouslylO; they are summarized in Table I. With unlimited time allowed between game turns, SKIRMISH requires one to two hours to play; AMBUSH requires three to eight hours. This time can be reduced substantially if limits are placed on the amount of time between turns. Due to both the length of play and the variability of human interaction, neither version is appropriate for use in generalized parametric sensitivity studies. Thus, for analysis purposes, the game is coolplementary to and not a substitute for computer simulation models. 2- 9 In the absence of any substantial interest in AMBUSH, it was decided not to proceed beyond the rough draft stage with its development.

Description of the SKIRMISH Tactical Board Game SKIRMISH simulates the hypothetical conflict between a truck convoy and an adversary group attemptinq to hijack its carqo. It is designed to familia ize users with basic concepts and important features of a road transit physic protection system without the necessity of understanding the total complexiti of AMBUSH itself. SKIRMISH has been desiqned as a two-player qame--one player commands the convoy, the other the adversary group. Additional players could participate by directinq various subqroups (e.q., individual vehicles or qroups of persor in the convoy). The conflict simulation is carried out on a game map that represents the terrain at the battle site. The map furnished with the game is shown in Figu Each turn represents one minute in the engagement. The opposing players dire the movement and actions of their pieces using their judgment of the situatic determine the best course of action. The outcome of random events, i.e., whe a piece is killed or wounded when shot at, is simulated through a combat resc tion table and the throw of a die. Flexibility has purposely been built intc basic structure of the game so that a user familiar with the fundamental cone can adjust the details to suit his particular situation. Factors which would be included in the AMBUSH version of the game are: different terrain types, the stopping of the transporter, the arrival of re­ sponse forces, removal of SNM from the transporter, additional weapon system~ routes, convoy confiqurations, vehicle vulnerabilities (including armor and cargo removal deterrent devices), size of opposing forces, and their arrival times. Additionally, human factor elements associated with suppression and panic can be in cluded in an elementary manner so that some insight can be qained into their effect on the battle. After the opening scenario has been defined the game proceeds, turn by turn, until one side is successful. Each turn is broken into four separate phases: (1) Planning Phase, (2) Combat Resolution Phase, (3) Movement Phase, and (4) Maintenance Phase. During each phase, ohly certain tasks can be per­ fornled by the qame pieces. Within each phase all action is considered to be simultaneous, i.e., somebody can be killed and still fire his weapon if he was plotted to do so in that game turn. In the Planning Phase, all tasks to be performed during that game turn are plotted by each player. Casualties are determined in the Combat Resoluti Phase. The outcome depends on defense strength as well as attack strength. Attack strength considers weapon type, range, and the condition of the firel Defense strength,considers possible cover, posture, and target movement. ThE roll of a die introduces uncertainty into combat resolution. In the Movemen1 Phase each player moves his pieces as casualty status permits. In the Main­ tenance Phase such tasks as barrier work and weapon exchange are conducted. At the completion of the Maintenance Phase, that turn is finished and the gan clock advances one minute to the next turn. For each game turn, a permanent record is made of all actions planned and executed. This enables the player! to later examine the effect of their actions on the battle1s outcome.

One shortcoming of playing board games with a single map is that each player has complete information about the position and movements of the oppos­ ing player's pieces. In actual combat each force has limited information about its opponents. The flexibility inherent in a board game allows the use of two maps with each player seeing only one. On his map, each player tracks his units plus those opposing units which he has located. A referee is required to determine which units have been identified. TABLE I

One escort vehicle, I , is one kilometer (40 hexes) ahead of the transporter and the other is one kilometer behind the transporter (off the map*). There are three defenders in I'ach vehicle. The six adversaries, A, have taken up positions with three at the upper left near the top of a steep hillside; two are to the riqht of the transporter in the trees, and one is in some bushes to the left of the trans­ porter. The adversaries chose these positions because they all offer unre­ ';tricted visibil ity of the, road and some defensive protection. )

Four of the adversaries are work­ ing on the vehicle's cargo barriers; the remaining two adversaries have remainE in position so as to detain any escort defenders who come to the transporter's aid. In the meantime, the defenders from the lead escort vehicle DE have stopped up around the bend in the road, dismounted, and moved up to the top of the hill from the rear. One of the adversaries who is watching up the road for the escort vehicle is wide open for attack. Figure 5 shows the resulting situation at the end of that game turn. Two of the three defenders on top of the hill have fired and killed the adversary on the hillside and have moved down the hillside. The healthy transporter crew member in the trees has moved up to attack the four adversaries working on the barrier. In the next few turns the defenders, positioned along the top of the steep hillside and at the edge of the woods, kill the adversaries working on the barrier. The engagement was completely resolved in favor of the defenders before the second escort vehicle came into play.

Feedback From SKIRMISH Users

ork­ emained ter1s

A draft version of SKIRMISH was distributed to a cross-section of organi­ '.ilions as well as internally to a range of individuals within Sandia. Their '1llIunents were incorporated into the version of the rules contained in this re­ 11I11't. In general, user's feedback fell into three separate categories.

op road

a. Requests for Added Detail--Several users suggested specific areas where they felt that additional detail or player options would add increased realism to the game. It must be remembered that the pur­ pose of SKIRMISH is to introduce newcomers to the use of a combat board game, to familiarize them with the major features of the road transit safeguards system, and to emphasize the influence of combat tactics on battle outcome. It is not intended that SKIRMISH treat any combat situation in detail. This is left to AMBUSH, the ad­ vanced version of the game, into which almost all the suggestions can be easily incorporated.

Two sary r crew n the f the on nders

b. Requests for Additional Flexibility--It is unlikely that the rules for either SKIRMISH or AMBUSH will ever cover all possible road transit safeguards situations. The present games are intended to serve as a framework to which users can add, subtract, or change to suit their particular needs. In this sense, flexibility is limited only by the creativity and motivation of individual users. c. Requests for a Refereed Game--During normal play of SKIRMISH and AMBUSH both defenders and adversaries work with the same game map. Consequently, both have full view of the battlefield and access to information on the deployment of their opponents which might not be available to them if they were actually on the battlefield. This problem can be eliminated with the use of separate maps by the defender and adversaries with a referee who determines what information should be on each map based on his perception of what would actually be available on the battlefield.

Introduction to AMBUSH Development

While SKIRMISH can be used by itself as a training or analysis tool, it i'.o serves as an introduction to the more detailed road transit tactical board 'Idille AMBUSH. Preliminary development of AMBUSH has been completed at Sandia 1,t1>oratories, Livermore (SLL) and the basic concepts val idated. Because of III(' redirection of the NRC transit safeguards program it was decided not to I

19

pursue final development of AMBUSH. If the decision is made to continue AMBUSH development at SLA, a rough draft version of the rules may be obtained from the SLL Central Technical Files, Division 8266, where it is stored on CTF Microfilm # BU-009. The additional game features outlined in the AMBUSH draft are discussed below. A comparison between the two games is found in Table I of this reporl. The principal differences from SKIRMISH are in the areas of terrain, attack scenarios, communications, cargo barriers, and response forces. a.

Terrain Three different maps were developed for AMBUSH. They correspond to flat, rolling hills, and forrested, mountainous terrain. Additional Ii for each map separate terrain densities and movement rates could be generated. In the draft version, this resulted in a total of nine terrain possibilities. Beyond these options it is possible for ex­ perienced players to use a map of their own choosing which corre­ sponds to a region of particular interest to them.

b.

Scenario In AMBUSH the players are encouraged to define their own scenarios so as to make the game as relevant as possible to their individual interests. If they prefer to use a standard scenario, six of them were constructed in AMBUSH, each designed to emphasize a different type of combat situation.

c.

Communications In SKIRMISH, the only communication assumed is that the escort vehicles have been notified of the attack on the transporter. In AMBUSH, two types of communications equipment were included with successful message transmission being a function of range. Citizen'" band (CB) equipment is used for radio communication within the convoy. and a long-range system with regional communication centers is used for communication between the convoy and response forces.

d.

Cargo Barriers In SKIRMISH, only one transporter barrier possibility is explicitly considered. AMBUSH contains four dlfferent cargo barrier possibil­ ities. The number of barrier penetration points required to gain access to the cargo vault depends on which transporter configuration is being penetrated.

e.

In

SKIRMISH does not contain provisions for response forces. In AMBUSH, response forces are available to come to the aid of a convoy under attack. The number of response forces available can be varied to reflect the dependency on location. Response force distribution cor­ responding to low, medium, and high population densities are available for each game scenario. Provisions can be made for communication delays if the responding forces are inadequately trained in the use of communications equipment.

AMBUSH, if fully developed, could be used as ,I ',,~curity system design/evaluation tool or possibly as part of an i!l depth f'lIl1iliarization program. SKIRMISH in its present form can be used as a train­ 111'1 tool. If its introduction were accompanied by some type of audio visual I'll'sentation to acquaint newcomers with the basic game fundamentals before 'Iu'y began reading the rule book, it could be usefully played within one day.

PROLOGUE

A principal objective of the Nuclear Regulatory Commission (NRC) is to protect the public from any misuse of the nuclear energy fuel cycle. Part of sat­ isfying this objective is establishing appropriate safeguards for the nuclear industry. To this end, one NRC program is establishing improved methods of protecting special nuclear material (SNM). As part of this NRC program, Sandia Laboratories, Livermore, Calif., is performing systems analyses to develop methods for evaluating protection schemes for the modes of transportation that could be used to move SNM bet~een facilities. To complement its computer simulation models, Sandia has developed the tactical board game AMBUSH, which is designed to simulate the attempted theft of SNM from truck convoys. Board games can give valuable insight into combat situations, since each player must make all decisions regarding the deployment and tactics of the units under his command. To computerize this degree of player in­ volvement would require development of an interactive graphic model, an expensive and time-consuming task with an end product which is difficult to share. On the other hand, AMBUSH and SKIRMISH (a simplified introductory version) are designed for a variety of players with diverse interests in the problems of safeguarding nuclear material. [1.0]

INTRODUCTION

AMBUSH is a hypothetical conflict between a truck convoy and an adversary group attempting to hijack its cargo. A broad range of scenarios and relative strengths between the two opposing forces is possible. AMBUSH has been designed as a two-player game; one commands the convoy, the other the adversary group. Additional players may participate by directing vari­ ous subgroups (e.g., vehicles and their personnel in the convoy). SKIRMISH, a simplified introductory ver­ sion of AMBUSH, is designed to familiarize players with basic concepts. To add more realism to the information available to each player, a referee may be used with either vers i on.

when at least one adversary gains access to the transporter vault. A defender win occurs when all adversaries have been killed, or when 20 game turns (20 simulated minutes of combat) have elapsed with­ out at least one adversary gaining access to the transporter vaul t. Other stopping conditions can bl' substituted upon mutual agreement by the players. The scenario is outlined in Figure 1.

Figure 1.

SKIRMISH Basic Scenario

ADVERSARY: 6 individuals armed with pistols and either semi-automatic rifles or shotguns. DEFENDERS: 2 modestly armored escort vehicles and 1 transporter vehicle with some armor pro­ tection and physical barriers to the cargo com­ partment; 7 guards armed with pistols and either semi-automatic rifles or shotguns. CONVOY CONFIGURATION: 2 guards in each vehicle, and a convoy commander (third guard) in a vehicle chosen by the convoy player; 2 escort vehicles placed at any distance up to 500 meters (20 hexes) in front of or in back of the transporter. CONVOY ROUTE: Either Route 4 or 7, chosen at the start of the game. AMBUSH POINT: Transporter stopped at a point (hex) chosen by the adversary player. VICTORY CONDITIONS ADVERSARY:

Accumulate 200 barrier points.

DEFENDER: Kill or wound all adversaries, or pre­ vent the adversary from accumulating 200 barrier points within 20 game turns.

[3.0]

GAME EQUIPMENT

[3.1] [2.0]

The SKIRMISH game simulates a battle in which a group of adversaries attempts to ambush and penetrate a transporter carrying SNM. In the basic scenario which is used to introduce players to the game, the battle takes place in hilly, rural terrain. There are 6 adversaries and 7 convoy defenders, each armed with a pistol and either a shotgun or a semi-automatic rifle. At the start of the game the transporter is immobilized at a place of the adversary player's choice, and the two escort vehicles, located up to 500 meters (20 hexes) ahead of and behind the trans­ porter, and moving in the same direction, have been notified of the attack. An adversary win occurs

Game Map

OBJECTIVE The 18"x24" game board upon which SKIRMISH is played represents the terrain surrounding the battl.· site. The terrain is either open ground or green, wooded area. Steep portions of hills or bluffs are represented by darkened boundaries. Contour lines are included to indicate elevation. Although they are not used in SKIRMISH itself, they are used when the terrain map is computerized for the SABRES II (5, II) combat model. The board contains two north­ south highways; each traverses different arrangement, of terrain features. The land surface is broken intI> hexagonal units, called hexes, each representing 25 meters of terrain. The grid is used to keep track ur the positions of the playing pieces. Each hex has do

allowance; however, all 10 points need not be taken. Table II lists all activities allowed in SKIRMISH and the associated number of activity points. Tasks must be combined and performed according to the sequence of play; combat, then movement, then maintenance. Every person in a vehicle must deduct from his total of 10

points any activity points used by the vehicle. For example, if the vehicle uses 4 points in moving 12 hexes and coming to a stop, then each individual in the vehicle has 10-4=6 points left for his use. The Activity Chart is used to keep a record of the action of each counter.

In each game turn the players plot their activi­ ties using the task codes (for example, OF for direct fire, MP for movement), the location the activity is directed toward or moved to, and the number of activity points expended. Chart A shows an example activity plot. The chart also provides a space for noting the end conditions (END) of each turn, which are recorded in the final task of the maintenance phase. the ambush point is announced and the Activ­ ity Charts for game turn 1 are completed, all counters are placed on the board in their designated positions. Since the adversary force ambushes the transporter but does not know the precise location of the escorts, in the first turn direct fire is allowed only by the ad­ versaries against the transporter. Direct fire against the escort vehicles or by the defenders cannot be planned until the second game turn.

Constraints on Activities

Off-the-Board Movement In SKIRMISH, once any counter is on the game board it cannot be removed. Personnel counters can­ not be moved to positions off the terrain map and later returned. Depending upon the location of the ambush point chosen by the Adversary Player, one of the escort vehicles may not be on the board at the start of the game. Personnel are allowed to exit from such a vehicle if it is stopped before reaching the game board and they choose to do so. (The number of hexes the escort vehicle is beyond the edge of the game board should be recorded on the Activity Chart.) However, once a vehicle has been plotted to move onto the game board, it cannot later be moved off.

* Blocked if LOS passes through the dark hexside. Personnel-in-Vehicles If the driver is killed or wounded, a moving vehicle moves an additional 2 hexes and stops. In order for the vehicle to move again, a healthy indi­ vidual must replace the driver (5 Activity Points). In SKIRMISH, personnel in vehicles cannot fire while the vehicle is in motion. (Fire from moving vehicles is assumed to have very little chance of hitting a target.) All rifles are considered to be loaded with armor penetrating ammunition. Shotguns and pistols cannot penetrate the vehicles and thus have no effect on occu­ pants. Weapons have no effect on the vehicle itself. In SKIRMISH, adversaries are not allowed to enter vehicles occupied by defenders or vice versa. [6.0J

A man cannot fire at any man he cannot see. The ability of a man to see from the hex he is in to some other hex depends on the terrain encountered by the Line of Sight (LOS), which is defined as a straight line drawn from the center of the observer hex to the c~nter of the target hex. Al I terrain features are described as either blocking or clear in their effect on the LOS (see Table III). If the LOS begins and/or ends in d blocked hex, counters can be sighted pro­ vided tnat no blocking hexes were encountered in be­ tween. It is not possible to see a counter one or more hex9s t'ehind a hlocking hex (Le., trees, slope hexsidf', or a hex with a vehicle in it). In other words, one can see into the edge of a group of trees or a steep hillside bu" not b2yond. For example, in Figure 3 man "A' on hex 0620 has LOS to man "X" in hex 1324 and man "'{' in hex 1219 hut not to man "Z" in hex 1624. Man "B" on 1327 has LOS to man "X" and "Z" LJut not to man "Y". The LO~ is used in the game to prevent fire (in either direction) when no LOS exists. Contour lines are shown on the SKIRMISH terrain map for illustrative pJrpose~ only; they are not used in the board game itself.

34

COMBAT RESOLUTION PHASE

All combat in a game turn is considered to occur simultaneously. Thus combat results have no effect un­ til the end of the combat resolution phase. A man that is a casualty early in combat resolution continues to engage in any combat plotted on the activity plotted on the activity charts for that turn. To resolve combat, determine the attack strength and the defensive strength and use their ratio to find the outcome of the engage­ ment. Although not supp lied with the game, players mi ght find it convenient to keep track of defensive and attack strengths individually by game turn on a separate chart. Each attack against a given target is resolved individually. Thus if a single definding man is the target of several attacking men, all of the5e combats are resolved separately. The total strengths of the attacking units are not combined. Even if the defending man is "killed" before all the allocated attacks are executed, the remainder of the attacks may not be changed. The remaining (useless) firing men may not reallocate fire

This concept of redundant kills is not unrealis­ tic since in combat assessment of kills is not always immediately clear.

[6.2]

Attack strength depends upon the weapon being USI the range (in hexes) to the target, and the condition the firer, i.e., whether he is fit (unwounded), wound or in a vehicle. Table V lists the SKIRMISH attack strength.

When fire is directed into a hex that is occupied by more than one man, the attacking player will fire at only one man. The man who receives the fire must be designated on the Activity Chart. [6.1]

Example: In Figure 3, the attack strength if a" personnel are armed with semiautomatic rifles and un· wounded is:

Defensive Strength

Defensive strength is determined by a combination of the target's terrain at the start of the turn and the movement plotted in that turn. Table IV gives the defensive strength factor.

Casualty States and Effects

There are two casualty states: wounded and killed. The casualty state~ and their effects are described in Table VII. When a man becomes "wounded" or "killed," the appropriate marker is placed on top of his counter. Casualty status progresses from wounded to killed. Since a man may be attacked more than once in a game or game turn, he may suffer multiple casualties. Two wounds equals a kill. If a man is wounded in the combat resolution phase it affects performance in the movement and main­ tenance phases. Activities are performed in the or­ der planned at double the Activity Points plotted until the 10 point limit is reached. [7.0J

MOVEMENT

As with combat, all movement is considered simul­ taneous. All movement must be executed as plotted, casualty status permitting. Men or vehicles may never alter their movement in response to enemy movement within the game turn.

If a man has been wounded during the combat resolution phase, his expenditure of activity points is double that planned on the Activity Chart. The wounded man mus t be moved along the pa th 0 ri gina 11 y planned for him as far as the Activity Points remaining after combat activities will allow. Men may pass through a hex containing an adver­ sary or defender. More than one person may occupy the same hex. In SKIRMISH vehicles can move only along highways and escort vehicles cannot pass through the ambush hex. Men may enter or exit only a vehicle which is stopped. If a vehicle is moving at the end of a turn, it must either be stopped or moved some additional number of hexes on the next turn. Each man must expend a certain number of Activity Points to enter a hex; the amount is determined by the terrain in the hex he is entering and the hexside that he crosses to enter the hex. Terrain effects on move­ ment are summarized in Table VIII.

TABLE VII:

CASUALTY STATES AND EFFECTS

Fit (Unwounded) Movement and Combat and all other capabilities are unimpaired. Wounded (W)

(11 Activity Points necessary to accomplish all tasks are doubled (e.g .• moves at 1/2 speed). (2) Attack strength is halved at all ranges (see Table V). (3) Cannot work on barriers or drive a vehicle.

Place a wounded counter on all wounded persons.

Killed (K) When an individual is killed, place a killed counter on that person.

*In SKIRMISH, vehicles must move along roads. 6 hexes per Activity Point (-55 mph).

[8.0J MAINTENANCE This phase is divided into four tasks: (1) Re-ann Weapon, (2) Weapon Exchange, (3) Barrier Work, and (4) Game Turn Record. [8.1J Re-arm Weapon (2 Activity Points) A man must lay down his rifle or shotgun to per­ fonn barrier work. Adversaries who worked on the barriers in a previous game turn must re-arm with a rifle to be able to use it in combat in the next turn. All personnel are always armed with a pistol. Thus barrier workers need not re-arm in order to enter pistol combat. [8.2J Weapon Exchange (2 Activity Points) A defender always has his pistol with him. Any defender can take either a shotgun or a semiautomatic rifle with him when he leaves his vehicle. Later he can enter a vehicle and exchange weapons. He can also exchange his weapon with that of any wounded or killed defender. To accomplish the exchange, he must be in the same hex with that individual during the game turn the weapon exchange is to occur. Adversaries can ex­ change weapons with each other under the same rules.

1/6

They can move at a rate of

[8.3J Barrier Work (10 Activity Points) Barrier work may not occur before game turn 2. In order to initiate penetration of the transporter barrier, one or more adversaries must occupy the same hex as the transporter. Recall that a man must lay down his rifle to perform barrier work. The men accumulate barrier work points for each complete turn that they occupy the trans­ porter hex and are plotted to work on the barriers. Since barrier work requires 10 Activity Points, no other activity can be carried out while working on barriers. In SKIRMISH wounded men are not eligible to participate in barrier penetration. Any adversaries wounded or killed in the combat resolution phases cannot work on the barriers. When working on a barrier an adversary is assumed to be in the open and does not have the defensive strength of being within a vehicle. If a barrier penetrator is being fired at, fear or distraction may prevent him from performing any barrier work during that turn. For each barrier worker being fired upon, roll the die to decide whether he works on the barrier during the game turn. A 1, 2, or 3 means that he does; 4, 5, or 6 means that he is too afraid or distracted to work. After this procedure, total the number of actual workers and consult Table IX to deter­ mine the barrier work points acquired. The men gain access to the transporter vault when 200 barrier points have been accumulated.

VARIATIONS

The flexibility of SKIRMISH allows players to modify the basic game easily. For example, the num ber of defenders and vehicles and the number of ad­ versary men can be vari ed. The defender s forces Cilll be restricted to a limited total number of shotguns and rifles. The total number of barrier points re­ quired can be varied. These options, a much more ex tensive range of terrain, weapon choices, and initial conditions, plus the availability of response force~, are included in the advanced AMBUSH board game. I

One shortcoming of playing SKIRMISH using a sin'll. map is that each player can know more about the oppo'. ing forces than is reasonable in actual combat. Thi'. situation can be remedied by using two maps and alluw ing each player to see only one. On his map, each player tracks his units plus those opposing units whl" he has located. A referee is generally required to detennine which units have been restricted.

Two manual play board games, SKIRMISH and AMBUSH, a,.re described in detail . They are part of a broad-based research effort to develop evaluative methodologies for transportation safeguards systems. These games help provide insight into the value of additional vehicles, guards, cargo barriers, equipment, and tactics. The tasks that are executed at any game turn are based on a htunan interpretation of the current overall situation and on which strategies appear to optimize the chance of success. Due to the strong dependence of ,the outcome on the sequence of player decisions, the games may prove useful as a training device for a transportation guard force. An advantage over computer-based combat simulation models is that both SKIRMISH and AMBUSH are easily transportable and relatively inexpensive. The development of SKIRMISH (a simp I ified or introductory version of AMBUSH) is complete. A set of SKIRMISH rules, together with sufficient materials for the assembly of a complete game, are contained in the Appendix. A preliminary version of AMBUSH has also been completed, and the differences between the two games are discussed. If, KEY WORDS AND DOCUMENT ANALYSIS
