An Imperfect Jewel: Military Theory and the Military Profession

This article explores a perennial theme in the literature of strategic studies: the relationship between military theory and the military profession. It begins with a conceptual analysis of this relationship. It then investigates what military theorists themselves have had to say about the utility of their craft. It concludes by assessing the actual influence of military theory on selected individuals and institutions. The individuals are George S. Patton, Jr., and Ulysses S. Grant. The institutions are the United States Army and the United States Air Force in the late twentieth century. The fundamental finding is suggested in the title: military theory can indeed be quite useful in the maturation of military commanders and in the development of martial institutions, but it is not always necessary and by no means perfect. It should thus be studied assiduously but used with caution.     

Gorshkov's Gambit

This article is a portrait of Admiral Sergei Gorshkov, commander of the Soviet Navy for almost three decades, from 1956–85. The author, a retired US Navy admiral with a Harvard PhD in Russian studies who served as both defense and naval attaché in Moscow, draws on numerous face-to-face interactions with Gorshkov. He also explores Gorshkov's memoirs that were published recently in Russia but have not appeared in an English translation. The paper is not only a first-hand account of an important historical figure, but also a window into the world of military-to-military diplomacy and intelligence during the Cold War.     

基于DM2的体系结构可执行模型构建方法

基于元模型的体系结构设计思想和基于可执行模型的评估方法是体系结构领域研究的两个热点,但当前的研究没有将两者结合起来。文章基于DoDAF2.0提出的元模型数据(Meta-Model Data,DM2),将元模型的思想和基于可执行模型的评估方法相结合,分析了基于DM2的逻辑数据与可执行模型各构建要素的对应关系,构建了基于DM2的逻辑数据模型直接转可执行模型的过程框架,重点研究了如何直接从体系结构底层数据转可执行模型的方法,从而为进行基于元模型的体系结构可执行评估提供模型基础,也为进一步实现体系结构自动化验证评估提供技术支持。实例验证了文章提出的方法。

Waypoint analysis for command and control

Command and Control (C2) in a military setting can be epitomized in battles‐of‐old when commanders would seek high ground to gain superior spatial‐temporal information; from this vantage point, decisions were made and relayed to units in the field. Although the fundamentals remain, technology has changed the practice of C2; for example, enemy units may be observed remotely, with instruments of varying positional accuracy. A basic problem in C2 is the ability to track an enemy object in the battlespace and to forecast its future position; the (extended) Kalman filter provides a straightforward solution. The problem changes fundamentally if one assumes that the moving object is headed for an (unknown) location, or waypoint. This article is concerned with the new problem of estimation of such a waypoint, for which we use Bayesian statistical prediction. The computational burden is greater than an ad hoc regression‐based estimate, which we also develop, but the Bayesian approach has a big advantage in that it yields both a predictor and a measure of its variability. © 2004 Wiley Periodicals, Inc.
