A set of rules for World War II and the immediate post-war years, for scales from 1:300 micro armour (company level or higher, as a general guide) to 1:72 (platoon level) scale, published by Wargames Research Group (WRG).
They were first published in 1973 as a development of the 1972 rules "War Games Rules Infantry Action 1925–1975", and later split into two eras covering 1925–1950, and 1950–2000.
The variations, as published by WRG, are set out in the table: Year Title 1972 War Games Rules Infantry Action 1925–1975 1973 War Games Rules Armour & Infantry 1925–1950 1974 War Games Rules Armour & Infantry 1950–1975 1979 War Games Rules for Armoured Warfare 1950–1985 1988 War Games Rules 1925–1950: Wargames Rules for All Arms Land Warfare from Platoon to Battalion Level 1993 War Games Rules 1950–2000: Wargames Rules for All Arms Land Warfare from Platoon to Battalion Level
A computer-moderated adaptation of the 1988 edition was created by WargameSystems. This is claimed to preserve the WRG rules structure and key data while the software automates the mechanics of playing by these rules, hence saving time and increasing enjoyment of the game.
Core rules summary Philosophy
Paraphrasing from the author's introduction: "The rules cover the period from the introduction of the fast tank until the introduction of ATGM, AFV range-finders and accurate APDS... the emphasis is on tactics, terrain, command and control... These rules are set in the real world of rain and mud, dust and mirage. The battles they simulate are not fought by nicely painted models but by men who are tired, frightened, dirty and often cold and hungry... Equipment performance and troop capabilities are based on those reported by real fighting units, rather than theoretical or artificial sources... differences in combat effectiveness that are not substantiated by careful research or that are insignificant compared with random factors are given only the attention they deserve."
Sequence of play
Alternate.
Time scale
One friendly and one enemy move per five minutes. Each move partly overlaps moves preceding and succeeding it.
Ground scale
Varies depending on the figure scale.
Troop scale
One figure represents one real equivalent. Infantry figures are based together in elements of 2 or 3 to 6.
Dice
One six sided dice is used throughout the rules.
Command and control
Each company (and if necessary, platoon) is given a one word order—Recce, Probe, Attack, Defend, Delay or Support—that specifies its task and imposes any tactical limitations. Some orders require additional information such as an objective, a line of advance, or boundaries.
Orders can be changed during a battle by passing the new order(s) through the chain of command.
Communication
Command elements can communicate once with a superior command element, three times with subordinate command elements, and with all directly subordinate elements.
Range and effectiveness depends on method—Personal, Line, Radio, Written, Signal.
Troop quality
Troops are classified as Inept, Green, Stubborn, Dashing, Skilled, Thrusting, Fanatic or Irregular. These classifications can restrict choice of Tactical Modes (explained hereafter) and also govern reactions to casualties and overrun situations.
Tactical Modes
Command elements can choose how to fulfil their orders by declaring a Tactical Mode – Salvo, Hold, March, Attack, Assault, Dash, Stalk, Skirmish, Slow, or Gap. Each Tactical Mode has its own movement and firing specifications.
An element's choice of a Tactical Mode can be restricted by orders, troop classification, terrain and combat results.
Exigency Modes
These are the same as Tactical Modes except that they are imposed while specific circumstances apply, such as being shot at. When these cease, elements revert to their Tactical Modes.
Firing
For direct fire, first dice to check for full or partial acquisition, specify the type of fire—Aimed, Volley, Suppressive—then dice to see if the fire is effective.
Area fire is not dissimilar to the above except that - Area fire resources are allocated Under Command, In Direct Support, In General Support, to Counterbattery, or at Priority Call. These classifications determine responsiveness to requests for fire support (which may not always be approved when required and may sometimes be supplemented by additional firers). Firing tasks are defined as Counterbattery, Programmed, Defensive or Impromptu. Each type of task has its own requirements for availability and activation. Targets are classified as Registered, Observed, or Predicted; these classifications affect aiming point accuracy and corrections. Possible fire patterns are Bombardment, Fireblow, Harassing, Concentration, or Barrage. These patterns have their own availability requirements and affect beaten zone dimensions and munition effectiveness.
Combat results
Successful fire causes the target to be Suppressed or Neutralised. Then check for Knock-out.
When carrying out Attack or Probe orders: Neutralisation may cause a platoon to become pinned Pinning or Knock-out may cause a company to become repulsed (which in turn may require it to retreat or change to Hold orders).
Regardless of orders, overrunning may also cause retreat or surrender results.
If all of a company's troops retreat in the same move, a rout may ensue.
Repulsed, retreated or routed troops must be rallied before they can advance or be given a new order, as must troops that have attacked and occupied an objective.
