As promised here are my Poms (oops, I mean Brits, ah English ... well I am an antipodean.)

We have a mixture of forces, with FV432s, Chieftains, Chieftains with stillbrew (my own scratch build), Warriors and Challengers, Abbots and M109s.

Now, I don't actually have all of there Brigades.  They're showing some of the options that I have. Pretty sure that I can field a full Division in various configurations though.

I realised that I didn't get a picture of the Corps troops - mainly the Artillery.  That will have to be for a later date.

It also occurred to me that, while these pictures give the broad brush of my forces, it might be of interest to do some close-ups of a selection of these models.  For another time.  Cheers till then.

The Notion of Force Points - Revised

Force Points

The key decision to make the campaign go forward is to describe the forces available for each side to use. This will be achieved by the use of Force Points (FP), tables describing the FPs available, NATO's responsive to attack and Force Tables setting out the forces available for use on-table. Further, a decision tree will set out how choices are to be made between the Attack Options, whether the attack was from a Gradual Build Up or a Standing Start, and NATO's response.

The aim of Force Points is to provide a resource to be allocated by the player to determine the type and number of  sized forces available on-table. The Force Points allocated generate that number of rolls on a Forces Table to determine on-table forces. The Forces Table will reflect the Sector, Battlespace and time period.

Force Points are calculated as the number of divisions available in Western Europe for each side divided by four. For example, the hypothesised Attack from Peacetime Posture outlined in the intelligence report 'Warning of War in Europe', June 1984, suggest only about 12 divisions would be available from the Group of Soviet Forces, Germany (GSFG), giving 3 Forces Points. The player would then allocate these points amongst the three sectors. When determining the forces available for a battle in a sector the player rolls a number of times on the Forces Table equal to the points allocated to the Sector.

A matrix table of available FP needs to be constructed. The following process was used to achieved that table. In the intelligence report 'Warning of War in Europe', June 1984, four Attack Options were identified as possible for a Warsaw Pact attack on Western Europe. The report also suggests for each Attack Option the likely total number of Warsaw Pact divisions available for each option, as well as the time need to operationalise each Attack Option and the likely warning that NATO may receive. This is outlined in Appendix 1 at the end of this post. As noted above, the Attack from a Peacetime Posture option suggests a minima of 12 divisions for the Forces involved. Attack Option 4 – Attack with Five Fronts, offers the maxima for those forces at about 90 divisions.

The boardgame 'Third World War' by Games Designer Workshop provides an Order of Battle and a timeline for the initial and follow-on echelons for the Warsaw Pact and NATO. The scale of those forces matches Attack Option 4 – Attack with Five Fronts. Making several leaps of imagination I filled in the blanks for the other Attack Options. The result is Table 1 – 'Forces Points Availability by Attack Options' which outlines the Force Points available for each Battlespace for each of the four Attack Options.

* Susceptible to shock; ! Susceptible to unavailability of forces; # allocated to Sectors 1 & 2 for Battlespace 1, a 50% chance of 1 FP for Sector 3


There are three modifiers to the figures in the table. These potentially reduce the available forces and their quality – making the seeming parity between NATO and Warsaw Pact forces less the case in reality. Firstly, forces may be susceptible to shock, due to the compressed nature of warning, leading to difficulties for command and control. Secondly, there may be unavailability of forces. Asking a question on the Yahoo TOandE group elicited several responses that suggested that NATO troops, especially the Bundeswehr, may be widely dispersed. On a weekend, perhaps only a third of a units forces may be able to speedily get back to base, in the context of the Attack from a Peacetime Posture option. The more warning the easier it is for NATO to get in position. The third modifier, that is specific to the opening moves of the Attack from a Peacetime Posture option, is that the forces available for an attack in Sector 3 which consist of the Central Group of Forces are represented by a 50% chance of one FP. The remaining FPs can be allocated between Sectors 1 and 2.

The first Battlespace will be influenced by NATO's political response to Soviet War preparations, which leads to Table 2a – 'NATO Response to War Warning in Europe by Attack Options' which roughly describes the available number of divisions available by the Attack Option and by three levels of response by NATO. It has been assumed that Soviet preparation time for each option is at the 'realistic' level. The NATO response is keyed to these preparation times with the 'active response' at the lower bound of the Soviet preparation times. Table 2b is the expression of these responses as FPs.

Determining Attack Posture and modifiers to Force Points

To determine how all these elements hang together and produce the end result of a set of FPs for allocation and forces chosen the following decision tree is used. The decision tree includes an option for the Non Soviet Warsaw Pact forces being unwilling.
  1. Roll for Attack Option, using a D10:
    1. Attack from Peacetime Posture 1
    2. Attack on Two Fronts 2, 3
    3. Attack on Three Fronts 4, 5, 6
    4. Attack on Five Fronts 7, 8, 9, 0
  1. Roll for whether the Attack had been from a Gradual Build Up or a Standing Start using a D6, 1-4 Gradual Build Up; 5, 6 Standing Start. The results affect the Force Points available, although some Attack Options may have minima/maxima:
    1. Gradual Build Up – brings Force Points forward to the first Battlespace:
      1. Roll a further D6, 1 = 0; 2, 3, 4 = +1; 5, 6 = +2 additional Force Points for Battle 1, these are subtracted from Battle 2;
    2. Standing Start
      1. No change.
  1. Roll to determine NATO responsiveness (refer Table 2b for the effects)
    1. Gradual Build Up - Roll a D10
      1. 1-4 = Active Response (immediate response)
      2. 5-9 = Measured Response (typical response)
      3. 0 = Tail Chasing Response (delayed response)
    2. Standing Start - Roll a D10
      1. 1-2 = Active Response (immediate response)
      2. 3-7 = Measured Response (typical response)
      3. 8, 9, 0 = Tail Chasing Response (delayed response)
  1. Unless considering the willingness of Non Soviet Warsaw Pact now allocate Force Points to each of the three Sectors.
  1. Consult the appropriate Forces table for each Sector. Roll on the Forces table for each Forces Point to determine the forces available.
Optional:
Roll to determine whether Non Soviet Warsaw Pact (NSWP) forces are willing or not. The probabilities are affected by whether there was a Gradual Build Up or Standing Start. These are deducted from the Warsaw Pact Force Point totals for Battlespace 1:

Gradual Build Up -
      1. NSWP Willing 1-8
        1. No change to Force Points
      2. NSWP Unwilling 9, 0
        1. Roll a further D6, 1, 2 = 0; 3, 4, 5 = -1; 6 = -2 Force Points
Standing Start -
      1. NSWP Willing 1-5
        1. No change to Force Points
      2. NSWP Unwilling 6-0
        1. Roll a further D6, 1, 2 = -1; 3, 4 = -2; 5, 6 = -3 Force Points
 An example of the decision tree is as follows:
  1. Attack Option - Roll a D10, the result is a 5.  Therefore there will be an Attack on Three Fronts;
  2. What Buildup - Roll a D6, the result is a 4.  Therefore there was a Gradual Buildup;
  3. Effect of Buildup - Rolling a further D6, the result is a 6.  This means that there are an additional 2 FPs in Battlespace 1 but 2 less in Battlespace 2.  Therefore the FPs available at this point for allocation by the Warsaw Pact are: Battlespace 1 = 10; Battlespace 2 = 2; and Battlespace 3 = 3.
  4. NATO response - Roll a D10, the result is a 6.  There is a measured response, meaning that NATO in Battlespace 1 had 6!() FPs.  So there are 6 FPs but they're susceptible to unavailability of forces, losing up to a third.  Battlespace 2 = 3 and Battlespace 3 = 2.
  5. NSWP Willingness - Roll a D10, the result is 7.  Therefore the NSWP are willing and there is no change Force Points.
The resulting Force Points for allocation amongst the three Sectors:
Warsaw Pact - Battlespace 1 = 10, Battlespace 2 = 2, and Battlespace 3 = 3;
NATO - Battlespace 1 = 6!() [4], Battlespace 2 = 3, and Battlespace 3 = 2.

A possible allocation may be:


WP/NATOSector 1Sector 2Sector 3

Battlespace 2

Battlespace 3

So a battle in Sector 1-Battlespace 1 involves four rolls on the Force Table for the Warsaw Pact and two rolls on a Force Table for NATO, adjusted for unavailability of forces.

The Force Table

Below is an example Forces Table, that for Sector 1 – Battle 1 for the period 1976 to 1980.  I had started to create a table covering individual years, with probabilities for troops, vehicles and weapon systems.  While more fine grained, with more variations, it really was a bit over the top.  Hence the table below, which is just a D10 roll and there you have a regiment sized force.  I intend to create three tables for each Sector-Battlespace covering three time periods.  A total of 27 tables, a set for each of the combatants.

The Future

There are still more elements to be established.  These include:
  1. defining in game terms the effects of being 'susceptible to shock' and 'susceptible to unavailability of forces';
  2. how to deal with the recovery of FPs at the end of a battle;
  3. how to define battle posture and adjustments to the forces resulting from the Force Tables;
  4. reflecting the impact of the Attack Options on the support units available, particularly engineering and artillery;
  5. designing a process for airpower and strategic strikes and their influence on-table;
  6. how progression, or not, through the Battlespaces affects posture and FPs in subsequent Battlespaces;
  7. an idea that the forces faced in each sector maybe variable, such as Sector 1 having possibilities for engagements with West German, Dutch or  British forces, or Sector 3 having US Army or Bundeswehr.
There are probably more but these will probably emerge as I work on the above elements.  Ideas for these elements already exist but need to be fleshed out and completed.  Finally, as a repository for my ideas, I may edit these posts later.  I'll try and leave a paper trail.

If anyone has any comments on the settings and proportions that I've used, I'd appreciate them.

So, until next time, probably with my Brits.
