Letter to the Editor-A Modification of Lanchester's Equations

The familiar Lanchester square law attrition model assumes that the attrition produced by a force is independent of enemy force size. This assumption may require modification if the larger force suffers inefficiencies of scale when force sizes are grossly unequal. A modification that alters relative force attrition capability by a factor depending on the force ratio is introduced and discussed in terms of a special case.
