RUSI Article - Measuring Lethality: Army Combat Power and Force Design (Not a Good Day for Lanchester)

A friend sent me a link to this interesting RUSI article, which ruminates around the topic of - "if you cannot be as big as the enemy can you be "bad ass badder than them instead". This is "bad ass as" in "more lethal" .. so are we talking Tiger tanks against Shermans again? Please read on to find out more and what it means for the UK against the Russian threat (see link below):

It also seemed to suggest policy making and reality are remarkably different, especially if you pretend everything boils down to an equation!

To quote from the paper (on page 27): 

The concept of the Lanchester Equation, modelling the relative accumulation of advantage of an aggregate force as attrition is suffered in engagements[39], is perhaps the perfect demonstration of a very sound theory when it is mathematically represented – with remarkably little utility in assessing any real-world military outcomes[40].

[40] Michael J Artelli and Richard F Deckro, ‘Modeling the Lanchester Laws with System Dynamics’, Journal of Defense Modeling and Simulation: Applications, Methodology, Technology (Vol. 5, No. 1, 2008), p. 7.

From 1916 to 2008 to 2026 the debate about Lanchester seems to go on and on. The problem seems to lie when people try and apply Lanchester as a general for all case, instead of when Lanchester conditions are met. The trouble is you only seem to know when these conditions are met, after the event. Then there is teh problem of retrofitting the data to suit your needs.

Note: People who "like Lanchester" don't seem to like wargaming as a participant but rather see it as a simulation "stand back" process where they are just dice chuckers. To me that if wrong, to wargame you have to take agency and responsibility. Anecdotally I keep seeing "Lanchestarians" losing their flanks and manoeuvring backwards on the table top. Harsh, but er, true!
