The burden and rigour of battle – Part 5

Capabilities

Battlefield decision-making in World War 2 was based on the assessment of terrain and other physical circumstances, the perception of enemy capabilities and intentions, and those of friendly forces. Tactical planning was traditionally derived from these assessments. Natural terrain was highly varied, and could be supplemented by extensive man-made enhancements, including concealment measures, obstacles, field and permanent fortifications, flooding, smoke, mines and booby traps. Many of these circumstances demanded specialist attention, through engineers, for example, or assault troops, specifically trained for a mission. The full spectrum of weapon types on the World War 2 battlefield included small arms and light support weapons, heavy support weapons such as mortars and heavy machine guns, tank guns, anti-tank guns, artillery and various flavours of air power. These weapon types gave troops the capability to project fire effects at different targets more or less efficiently at different ranges, through direct fire observed by the firer, and indirect fire, either observed by specialist spotters, or fired from map co-ordinates or at known positions. Air power by the end of the war gave the capability to carpet bomb large “boxes” on the ground with an effect similar to tactical nuclear weapons though without the radiation.

At company level and below, it was likely that troops would use or meet at any one time, only a limited range from the spectrum of weapon types. An infantry company would not contain all these weapon systems, but only the sub-set designated for use by an infantry company, primarily small arms, light and a few heavy support weapons. It might encounter other weapon types through specific support assets for specific missions, for example from artillery or armoured vehicles.

At the local level many weapon types might not be considered relevant, and modelling at this level can be considered less complex than at battlegroup level for this reason. For example, Phil Sabin’s excellent simulation Fire and Movement covers a 1943-4 WW2 British infantry battalion attack (12 rifle platoons and a machine gun platoon) against 6 depleted German rifle platoons. Weapon systems depicted include only small arms (primarily rifles and light machine guns grouped together), specialist support machine guns and off-map 3” and 8cm mortars. There is also a brief initial artillery bombardment by the attackers. The limit to the types of weapon systems included in the simulation is understandable, as it is “a simple grand tactical simulation of an attack by a British infantry battalion”, and it is designed to model “the interdependence of fire and movement” (quotes from Phil Sabin’s book, Simulating War). In support of my argument here, Phil Sabin admits that “Attacks would usually be supported by divisional artillery and by attached tank platoons, but this would add significantly to the complexity of the system…”. In fact, I think that this simulation better illustrates the style of attack at infantry company scale than at battalion or higher levels. Though the introduction to the simulation states that it focuses “on the employment of Fire and Movement tactics to exploit and overcome the terrifying suppressive effects of modern firepower”, it deliberately does not include some significant weapon systems delivering those fire effects, explicitly to simplify the simulation.

Conversely at higher levels, the impact of different weapon systems has to be more abstracted in a model, because the wargame is likely to deal with the combat power of larger units, at divisional size or above. This combat power is usually represented by numerical values, and perhaps variation in movement capabilities for armoured units.

At battlegroup level, capabilities and encounters would often cover the full spectrum of weapon types, with the exception of aircraft, which were generally controlled in WW2 either by independent or semi-independent air forces or by commands at army or higher level. Decisions at battlegroup level were therefore based on this full spectrum of weapon types, and it was the interplay of the weapon types and the efficient use of their combined effects that had a direct impact on the combat effectiveness of both sides and therefore on combat outcomes. At this level, co-ordination of the people with the different weapons systems was vital for maximising combat effectiveness against identified opposing people with their weapons systems. It is how to model this co-ordination, or the lack of it, that forms a critical part of the difficulty of wargame modelling at the battlegroup level.

Taking the Normandy campaign as an example, both sides had difficulty getting to grips with the terrain, especially the bocage country. New units invariably went through a learning process. On the Allied side, units were either green, having arrived from the USA or been recruited and trained in the UK, or were from a very different theatre, primarily from North Africa, and experience there was of little help in Normandy. On the German side, experience was primarily from the Eastern Front against the Soviet Army, where space could be traded for time, and the nature of combat was quite different from the close terrain and restricted beachhead conditions of Normandy, coupled with overwhelming British and US air and artillery dominance. These conditions at variance from expectations led to a gap between the doctrine in the books, the training and past experience on the one hand, and actual practical application of combat capabilities in Normandy on the other. For the Allies there was an initial expectation that the Germans wouldn’t defend, or at least, wouldn’t be able to defend, right at the beachhead, so that a mobile armoured style of warfare could be adopted, where the Allies’ fully motorised forces, coupled with air power, would have the edge. When this expectation failed to materialise early in the campaign, the lack of a combined arms doctrine from the British and the lack of experience of the US troops, added to the complexity and confusion in the practical application of the various weapon systems. For the Germans, few of their troops had experience of fighting against the British and Americans – very few units had any experience from Italy, which would have been relevant, and commanders from that theatre were not used much in Normandy. They also failed to apply their own operational and strategic doctrine effectively, partly due to interference from Hitler and others in the high command. This background demonstrates the complexity of implementing combined arms combat methods at battlegroup level in Normandy, and there is no reason to believe that other theatres and time periods in WW2 were less complex. Modelling this level of complexity is problematic. If critical elements are over-simplified or abstracted, incorrect inferences might be drawn from the model.

Modelling the effect of the combinations of weapon systems is necessary at battlegroup level, if we are to achieve insights from the modelling. Effects required include the destruction of vulnerable enemy forces by artillery, air power, and direct fire from tanks and other armoured vehicles; the suppression of defences before and during attack by artillery and direct fire from heavy weapons, finding out where the enemy is and isn’t (reconnaissance, including combat reconnaissance), finding and exploitation of gaps (reconnaissance and armour for speed, infantry to follow up in vehicles or not, and to hold ground), concealment (engineers, and the skilled deployment of infantry and other troops), protection from and destruction of armoured attack (anti-tank guns, hand-held anti-tank weapons, medium and heavy artillery, naval guns), destruction of infantry attacks (artillery, other support weapons, such as machine guns, mortars), defence from air power (anti-aircraft guns), creation, maintenance and enhancement of defensive positions (infantry with supports, plus minefields and other obstacles). Omitting some of these weapon systems from the battlegroup level model may result in false conclusions.

For example, if we omit the use of relatively few, relatively static armoured vehicles in defensive situations from our model of late war combat, we might conclude that defensive positions can be fully compromised in depth by artillery bombardments closely followed by armoured attacks with infantry support and a sufficiency of heavy weapons for direct fire suppression. Examples from late in the Normandy campaign (Operations Totalise and Tractable) tend in that direction, and led to conclusions about the efficacy of attacks using armoured infantry fighting from within their vehicles. However, it is clear from German evidence that, wherever possible, their positions were supported with relatively few, relatively static armoured vehicles, because without these, their scanty infantry forces did crack, even though the combat power of the very small number of vehicles might seem insignificant.

Different weapons systems were often in different units for command and control purposes. So, co-ordination via inter-unit communication was essential, for without this, disaster could happen. Modelling this aspect of combat is also critical.

Some examples from the Normandy campaign may help to illustrate this importance. On 7 June 1944 Canadian 9th Brigade continued with its D-Day orders, despite the circumstances having changed for the following day. Their advance was a narrow one by an infantry battalion operating as an advanced guard lacking in close anti-tank gun and artillery support. Though there was a supporting tank regiment, they were late coming up, and operated relatively independently down flanking roads, but without rigorous cross-country reconnaissance or co-ordination with the infantry. Accounts of the advance guard’s fate suggest little direction from brigade or division down to battalion level, a rigid adherence to a pre-set plan and insufficient co-ordination between infantry, tanks and artillery. Anti-tank and other heavy weapons were left in positions far back, where they were unable to support forward units, and the battalion command had to rely primarily on its infantry assets, being unable to co-ordinate the other arms, owing to failures of communication (with the artillery) and control (with supporting heavy weapons). In addition brigade was not able, or was unwilling, to deploy supporting units in time to prevent the forward battalion from destruction in detail. The advance guard was badly mauled and forced back to its start line by a strong attack from elements of the 12th SS Panzer Division.

Such failures of co-ordination were by no means the privilege of Commonwealth forces. The very next day, 12th SS Panzer Division’s highly rated and experienced regimental commander, Kurt Meyer, carried out a hasty night attack with a Panther battalion against the Canadians. His infantry support was limited to a small number of reconnaissance troops, because he had failed to ensure support from 26th SS infantry regiment, in front of the main target of his attack. Unsupported tanks were able to enter the target village, but lost many vehicles to accurate Canadian tank fire on the un-reconnoitred approach, and from anti-tank guns and PIATs within the built-up area. The attack was beaten off with loss.

It is difficult to model these actions in wargames. Wargamers, even armchair hobbyists, are unlikely to plan operations of this nature, because they may have already read the histories. In the cold light of day, they can appreciate the risks of unsupported advances and hasty attacks. Their own experience of wargames often exceeds the combat experience of real-life commanders, but the conditions of their combats are less stressful and therefore perhaps less prone to error.

Real life commanders at battlegroup level usually had some training at this level and often some experience, although the start of a campaign or the opening of a new theatre would frequently result in on-the-job learning from a low base. In most armies, training usually involved the inculcation of national doctrine. However, hobby wargamers usually don’t have this training or experience, and often have little background in military history. In addition, real commanders had more or less extensive staffs to help with planning, communications, logistics, intelligence and a myriad of other vital functions. Again, wargamers usually lack these experts, so much of the supporting infrastructure to the commander has to be abstracted in a wargame.

A couple more linked elements help to explain the difficulties of the human aspects of battlegroup level modelling: preconceptions and the fog of war. I’ll address those briefly in my next post.

The burden and rigour of battle – Part 4

Command, control and communications difficulties

Information could flow from sections, platoons and companies to battalion or brigade fairly quickly, owing to proximity, so decisions on action could be fast, usually verbal, and these levels of command could exploit tactical success rapidly. From there, communications upward to division and onwards were often slower. Distances were greater, the volume of information was greater, as it was coming from many subordinate units, and there was more analysis of the significance of information by staff on the way up. High command needed an overview of the situation, rather than excessive detail, so that it could give orders at divisional and corps levels, and this usually meant waiting for the big picture to come into focus. So, intervention from high command hour-by-hour was not usually carried out, and a wargame at higher command level can avoid the clutter of immediate communications friction by having longer game turns and representation of only larger scale units.

Examples include, on the Allied side, the need to wait for clarity of outcomes of the initial assaults on D-Day before changing orders (Dempsey’s halt order is one example). On the German side, the whole question of tardy intervention at the level of corps and above was influenced by a perceived lack of good quality information at that level of command, and particularly by Allied deception measures. Battalion, regiment and division commanders found this extremely frustrating, because they sometimes had clear and urgent information that they were unable to impress upon higher commands.

Information flow at battlegroup level was extensive. It was up, down and sideways to the flanks. Representing these information flows and their impact on decision-making at battlegroup level in a wargame model is tricky. In reality, communications took time. Either a commander or runner went to a command post to make or receive a personal briefing, often resulting in changes or clarifications of orders in response. Alternatively, telephone (landline) or wireless contact had to be made. Time was spent encrypting and decrypting messages, or in rare cases risks were run with messages in clear, using forms of verbal coding, such as code names for locations and units. Communications upwards went through many levels of the organisational hierarchy, with each level adding or taking away (or distorting) the messages, and each step adding to the time taken between initial transmission and receipt, let alone decisions on action in response. While direct communications between flanking units could be carried out relatively quickly, for example via liaison officers appointed to the task, co-ordination of the actions of units in different battalions, regiments, brigades or divisions, often required messages first going up the hierarchy, then back down a different strand of it. For example on 7 June 9th Canadian Brigade’s advance guard was unable to communicate directly with its supporting artillery regiments, and was also unable to liaise with additional available units that were not directly attached to it, because routing communications through brigade, division, corps, then to the full artillery command and control hierarchy proved impossible to carry out. This type of situation led to common difficulties in the meshing of activities at the joins between different divisions, corps and armies, and the vulnerability of troops at these joins. The British breakthrough in Operation Bluecoat was caused by a “joins failure”.

In place of this necessarily imprecise and sometimes flawed communications network, wargaming can have the problem of the “bird’s eye view”, where all those involved can see much of the contextual information about the situation on the tabletop or the board without the necessity for formal communications at all. Instead of difficult communications and combinations, it is often readily obvious to wargamers what actions could and should be taken, and an informal chat – “out of game” as it were – can resolve these difficulties without the modeller’s knowledge.

Command and control of subordinate units in the field was usually exercised in a formal sense, with command instructions flowing down the hierarchy, even though discussions between levels of command could and did happen. Wargaming, particularly hobby wargaming, is less serious than the real business of war, and the authority of senior versus junior commanders can be diluted, or in some cases, dissolved by the “game”. It’s rare that sanctions – such as dismissal on the spot! – can be taken, even in cases of gross violations of command and control norms, as this type of intervention by senior commanders or umpires could be seen to violate the social aspects of wargaming, and could wreck the continuation of the exercise.

Even more, the changing intentions of a group of players as a team on the same side, may be continually moulded and clarified by informal commentary during the wargame, in circumstances where communication and the exercise of command and control in the field would have been impossible. It is certainly possible to address this issue by arranging for the separation of command teams, or individuals, though difficult in hobby wargames. In one of our wargaming groups, we have regularly attempted to remove commanders-in-chief from direct interaction with the tabletop, so that communications about the current situation can only be via player interactions and reporting, but this is difficult to enforce. This should be easier in a professional wargaming environment with trained military personnel.

As we would expect, command, control and communications in a face-to-face wargame may be easier than on the battlefield, yet a wargame should attempt to model the real life difficulties. Typical solutions to this problem in analogue miniatures wargames have used player initiative points (PIPs), or some other method of randomising the vagaries of command, control and communications. In short, a dice is rolled or a card drawn, and the result is the activation of more or less units, or a specific but not predetermined sequencing of activation. This can reflect the inability of all units to act all of the time, or in the “right” order. However, there are difficulties with these outcome-based design solutions, because, though the effect may be to make the activity or inactivity of combat units look more “realistic”, a randomised method leads inevitably to the gaming of the probabilities concerned – “I calculate only a 1 in 6 chance of failure”, for example – rather than addressing the genuine concerns of communications, which were about both predictable and unpredictable delays, and friction caused by known factors, as well as by random ones. For example, the exercise of command and control during intense combat was more difficult than well behind the lines. A response to a request for artillery support may be delayed because of conflicting demands, but this is rather different from “I failed to roll a 5 or 6”, and seems pernicious if, in fact, the artillery was a dedicated support asset, on-call and with no conflicting demands.

The burden and rigour of battle – Part 3

Continuing my battlegroup wargaming article, “The burden and rigour of battle” – for earlier ones in the series, see the sidebar.

Here are few illustrative examples of what I mean about the significance of combat outcomes at various levels, drawn from the history of the early part of the 1944 Normandy campaign.

The D-Day assault itself was planned at high level, and plans cascaded down to units at all levels of command prior to the assault. In terms of the fighting, it was the actions at company level and below generally that established troops on the beaches. At the initial assault stage the higher levels of command, including battlegroup level, were very much dependent on their smaller units carrying out their assigned tasks within a matter of hours and even minutes. However, I suggest that it was decisions by battalion and brigade commanders (particularly the latter) that led to exploitation with decisive effect during D-Day itself. Decisions on where to put reserves were taken at divisional level (for example 3rd Canadian Division on where to put their reserve brigade). Decisions on where to push battalions were often taken at brigade and even battalion level (for example manoeuvres on the day around Courseulles, Bernieres and inland). The timing and precise routes of commandos coming off Sword Beach moving inland were directed on the basis of leadership from officers, such as Lord Lovat. 3rd British Division, it has been argued, was hampered by the more cautious than expected approach from its battalion and brigade commanders, so it wasn’t able to follow its plan. However, it was decisions at this level that were critical. Reports that ‘enemy tanks were advancing from Caen’ were relayed back from the Staffordshire Yeomanry via 3rd British Division to 2nd British Army. The divisional commander “ordered a battalion of 9th British Brigade to hold at Perriers-le-Dan and ensure that the Sword bridgehead could not be rolled up from the west”. Despite the fact that the German attack was stopped, the reports of German tanks directly influenced Dempsey’s decision to issue the order to halt his 3 assault divisions in place at some time after 7pm, in case of further counter-attacks. Here we have an example of battlegroup level command decisions and reports directly affecting higher command decisions, at variance to the overall plan.

6th Airborne Division’s brigades and battalions were mustered by battalion as they landed on 6 June, and led off on their missions at the instigation of battalion commanders. Precise timing was decided by battalion COs (or other staff if COs were absent), using their judgement as to how long they could wait for assembly prior to moving off to their positions. It was also battalion and brigade commanders who made the decisions about the details of their deployments, within broad constraints of divisional and brigade plans, but necessarily adjusted to the real-life circumstances on the ground that were sometimes at variance with the plans. Similarly, when US battalions were landed at the wrong places on Utah Beach, it was commanders at battlegroup level that adjusted the deployments to meet reality.

A potential counter-argument might be Operation Deadstick, the taking of the bridges over the Orne and the Caen Canal, which was a company level action, and was decisive. But it’s worth noting that this was a tactical implementation of a coup de main within the context of the wider Operation Tonga (the airborne landings) and subsequent vital relief operation at battalion and brigade level by 7 Parachute Battalion, 5th Parachute Brigade and commandos of 1st Special Service Brigade that converted the company level action into a firm left flank for 2nd Army. Battalion and brigade commanders made decisions on how to set up their defence within the context of the divisional plan, and brigade made decisions on how to manage reserves and switch manpower in the light of attacks.

The German side also provides illustrations of the importance of this level of command, and I’ll return to these examples in the context of wargaming later. 21st Panzer Division’s activities on D-Day were heavily constrained because, in the view of regimental commander Hans von Luck, vital decisions about movement were not taken; delays were imposed by paralysis from above. But, I would argue that there is a useful comparison between the relatively supine stance of 21st Panzer Division during the morning of 6 June, and the more pro-active command decisions by 12th SS Panzer Division. The latter’s assembly was accompanied by extensive reconnaissance and planning for deployment, whereas 21st Panzer Division’s reconnaissance battalion was almost its last unit to be deployed. Management of the 21st Panzer Division’s probes during the morning and early afternoon were handled entirely at regiment and battalion level, in the absence of coherent senior direction. So, actual combat decisions were taken at regiment and battalion – battlegroup – level, while more senior commanders were critically unable to impact the combat, and I would argue it was failures at battlegroup level that contributed to the Division’s relatively poor showing. The handling of the late afternoon and early evening counter-attack was by kampfgruppe commanders, even though the main force was initially accompanied by the corps commander. Each of 21st Panzer Division’s 3 kampfgruppe had from roughly a reinforced battalion to roughly regimental strength (brigade in British parlance). In response, British defence decisions by elements of 3rd British Division and supports, were taken at the same level. These included deployment on Periers ridge, movement of supports, the balance of infantry and tanks, and assessment of threat and risk.

Next… a bit more on command, control and communications difficulties…

Photoshoot 2

The photoshoot was successful! Many thanks to Neil and Pete. I now have over 200 images to fiddle with. In fact, thanks in advance are due to Charlie, who will be doing the fiddling :).

Our photos will be designed to illustrate the mechanics of the game. Looking at other rules I find it a bit surprising that there’s a tendency towards pretty diorama style photos that don’t really show the workings of the game, rather than illustrating how a more normal wargame might look. I suspect that’s because people like Osprey have a different focus; though Osprey does some nice drawn diagrams for their’s.

The “after” shot of the Panzer IV breitkeil is:

Distance overlay to be added. I prefer this because it’s more active and less like a diagram than the previous one.

 

The burden and rigour of battle – Part 2

Why might the modelling of combat at higher or lower levels be less problematic?

At higher levels (corps, army, army group, theatre), the focus of command was on the operational and the strategic. Decisions were vital at this level, but people in the higher commands relied on their subordinates at division and below to report on the situation on the ground and to carry out the nitty-gritty implementation of plans and variations on them. So, higher command decisions during a battle were dependent on the flow of tactical information to answer questions about how battalions, brigades and divisions were doing, and to provide information about the enemy. There was inevitably a loss of the granular detail of combat events in the transmission of information upwards, if nothing else to prevent overwhelming the senior commanders and their staffs with information, and thereby paralysing decision-making.

Reflecting this flow of information upwards in wargames at operational and strategic level means modelling through abstraction, typically through providing fewer unit representations (for example, counters in board wargames, elements, stands or blocks in wargaming with miniatures, unit graphics in computer wargames), and using numerical values to represent combat effectiveness, rather than delving into the characteristics of weapons or even of weapon types. In addition, time scales in game for operational and strategic level models are usually longer – a day, a week, a month – skating over detailed tactical events. These abstractions reduce the complexity of the combat aspects of an operational and strategic model, even if other elements, such as political context, logistics and strategic deployments, might make the overall strategic model more complex. Combat doctrine and the details of the organisation and utilisation of units below division level are generally not included, though they might be reflected in tweaks to the numbers. Examples of WW2 hobby wargames at this level include: World in Flames, Rise and Decline of the Third Reich, Axis & Allies, World War II: Barbarossa to Berlin, War in the East.

At a lower level – section, platoon, company – combat events were important for purely tactical outcomes, and there was only rarely operational or strategic impacts from the result of any single action. For the soldiers concerned, this was the sharp end of their personal experience, so I wouldn’t belittle its importance to them as individuals and small groups. However, in terms of the wider picture of combat outcomes and their impact on the results of operational and strategic engagements, decisions at the battlegroup level were vastly more significant. It is noteworthy that reading first-hand accounts from frontline soldiers who were not commanders at battalion or higher level, reveals little about the impact of small scale tactical engagements in the wider context of an operational or strategic action.

The complexity and type of wargames at the tactical level varies from the introductory (for a recent example, see Airfix Battles) to the highly detailed (for example Advanced Squad Leader) to the innovative (for example Up Front, Fighting Formations). The details of combat at the individual level are relatively easy to come by through the vast array of memoirs and first-hand accounts published and popularised. In addition, there is the canon of secondary sources to read and popular films to see. When we talk about World War 2 wargaming, this is very much the typical experience for players, and there are well-worn design mechanics, as well as significant innovation, in this aspect of the topic, with a lot of variation in the accuracy of the models, many preferring a good thematic feel and a high level of playability over realistic modelling of tactics. What might be referred to as “Hollywood wargaming” is the mainstay of tactical World War 2 commercial wargames design in board wargames, miniatures wargames and computer-based wargames.

There is a flood of examples of popular hobby board wargames at this level, including: Panzer Blitz, Advanced Squad Leader, Combat Commander, Memoir ’44, Tide of Iron, Conflict of Heroes and many more. Popular World War 2 miniatures wargaming rules include Flames of War, CrossFire, Bolt Action and many more.

There is also a small number of simulation wargames, rather than only thematic offerings. One example is Phil Sabin’s simulation game Block Busting, which models an attack by a reinforced infantry company in an urban area with the intention “to reflect more directly the key variation within the urban environment, namely the difference between the buildings, on one hand, and the open spaces…on the other.” This game is a variant of Professor Sabin’s game Fire and Movement. An important point about Block Busting is that it was designed with a specific purpose in mind, namely to model the problem of infantry combat in urban areas in World War 2, whereas the game systems of the earlier examples tend to be more generically about what could be termed “skirmish level” combat, often using unit sizes of 1 vehicle and a handful of men.

To follow, some examples from Normandy…

Achtung! Spitfeuer! Air combat in Open Battles

Open Battles update: Nick and I had a good session over the hols. We’ve focused on the basics at the moment. This is all about how to retain the essence of Airfix Battles within the context of a new Open Battles system without squares. We’re keeping the Unit cards, Command cards and the fundamentals of the combat system, so that the new game will be recognisably similar to AB – components will be compatible. But you’ll be able to use whatever WW2 miniatures and terrain you happen to have, or wish to acquire for the new game.

We are retaining the numerical movement points and ranges. These then convert into an appropriate distance on the tabletop depending on the scale of your minis. Typically, this would be 1 movement point or 1 range equals 4″ for 1/72 scale or 15mm scale figures. There’s a bunch of “how to…” things that we’ve drafted, which I’ll go into in a later post.

Open Battles will include Air Movement and Air Combat, and we’re looking for your comments on our current work. I’ve stuck a file called OpenBattlesAirCombat.pdf here, plus some aircraft unit cards here. Any comments would be very welcome!

The burden and rigour of battle – Part 1

As I’ve been developing Mission Command over the past 10 years or so, I like to believe that I’ve learnt something about wargames design, particularly in the field of WW2 land combat. There are probably some wider lessons learnt more generally, but I thought I’d focus a bit on some thoughts about modelling battlegroup tactics. Wolfgang Schneider has a relevant quote in his book Panzer Tactics: “The technical literature includes countless competent presentations at the level of operational / strategic command (army and higher). That also holds true at the tactical / operational level of army corps and division. Totally underrepresented are factually correct descriptions of the level of command that bears the actual burden and rigor [sic] of the battle, that of the regiment – generally, the brigade in modern usage and the battalion.

In World War 2, the level of command from battalion through regiment or brigade up to division was the level at which combat decisions and outcomes occurred that translated into decisive operational and strategic results. It was the foundation of, and implementation method for, operational and strategic decision-making interventions by the higher command levels. I have called this ‘battlegroup level’, as it encompasses formations variously called ‘kampfgruppen’, ‘combat commands’ or ‘battlegroups’, varying in size from a few companies up to whole divisions, and usually containing troops with a combination of different weapons systems.

I argue that designing wargames to model with reasonable accuracy the principal elements that impact decision-making with respect to combat at this battlegroup level is very challenging. It is perhaps more challenging than at higher, operational and strategic, command levels or lower intrinsically tactical command levels. Why this is so, requires some explanation, and may help to provide an insight into World War 2 combat and the modelling of it in this context. My approach is primarily using board wargames and miniatures wargames, rather than computer-based models. However, some of the general insights should also apply to computer-based models.

More to follow…
