Are They Channeling Trevor Dupuy?

Continuing the RAND description of their hex boardgame:

Ground unit combat strengths were based on a systematic scoring of individual weapons, from tanks and artillery down to light machine guns, which were then aggregated according to the tables of organization and equipment for the various classes of NATO and Russian units. Overall unit scores were adjusted to account for differences in training, sustainment, and other factors not otherwise captured. Air unit combat strengths were derived from the results of offline engagement, mission, and campaign-level modeling.

This looks like some kind of firepower or combat power score, or perhaps Trevor Dupuy’s OLIs (Operational Lethality Indexes). As they say “systematic scoring” one wonders what system they used. Know of only one scoring system that is systematic (meaning the OLIs, which are based upon formulae). The subject is probably best summarized in Dr. James Taylor’s article on “Consistent Scoring of Weapons and Aggregation of Forces:” http://www.dupuyinstitute.org/pdf/v2n2.pdf. This is the same James Taylor who wrote the definitive two-volume work on Lanchester equations.

I do note with interest the adjustment for “differences in training, sustainment, and other factors.” That is always good to see.

Also noted:

Full documentation of the gaming platform will be forthcoming in a subsequent report.

Look forward to reading it.

  3. “Full documentation of the gaming platform will be forthcoming in a subsequent report.”, has this appeared yet?

    • I just checked the RAND website and have not located anything addressing the methodology for that wargame. Maybe they forgot.

    • OK. Strange though, as it means others have no real idea whether the game was a valid basis for making a decision.

      • Between time and budget limitations; and sometimes other interests: be they marketing, bureaucracy, personal, and/or classification…it just never really happens.

        It is a major issue, but it never really gets fixed. I do touch upon this issue in my upcoming book War by Numbers.
