  Lanchester's model of combat has certain deficiencies in its standard form
arising from the neglect of the influence of random fluctuations. Several
approaches to rectify this have been proposed and various results are scattered
throughout the literature. Here, a discrete-time stochastic version, which is
amenable to exact solution, is revisited with the aim of deriving key results
within one setting. The exposition simplifies and provides refinements to
earlier derivations and analysis.
