Vicarious warfare: The counterproductive consequences of modern American military practice

This article examines contemporary modes of American warfare. It posits the concept of “vicarious warfare” as a means of capturing prominent patterns in warfighting approaches. Although rooted in long-standing traditions of military practice, vicarious warfare is sufficiently novel as to be identifiable as a distinct phenomenon. The precise manifestation or combination of vicarious methods vary according to the specific circumstances and political contexts prevailing in different theaters. However, America’s general preference is to fight its wars by delegating tasks to proxies and limiting exposure of its own military to danger. Where U.S. forces are employed directly, this takes place largely in the shadows. Such approaches have clear attractions, offer undoubted tactical advantages, and permit successive administrations to maintain a persistent tempo of operations that evades rigorous democratic scrutiny. Yet, prominent cases and numerous studies suggest that vicarious warfare has a high potential to generate counterproductive effects and significant strategic harm.     

Think again – supplying war: reappraising military logistics and its centrality to strategy and war

This article argues that logistics constrains strategic opportunity while itself being heavily circumscribed by strategic and operational planning. With the academic literature all but ignoring the centrality of logistics to strategy and war, this article argues for a reappraisal of the critical role of military logistics, and posits that the study and conduct of war and strategy are incomplete at best or false at worst when they ignore this crucial component of the art of war. The article conceptualises the logistics–strategy nexus in a novel way, explores its contemporary manifestation in an age of uncertainty, and applies it to a detailed case study of UK operations in Iraq and Afghanistan since 2001.     

MAD,not Marx: Khrushchev and the nuclear revolution

The revival of nuclear strategy in US policy and scholarship has been strengthened by arguments that the ‘nuclear revolution’ – the assumption that thermonuclear bombs and missiles had made major war too dangerous to wage – does not affect international behaviour as much as nuclear revolution advocates claim. This article shows that the Soviet leader Nikita Khrushchev indeed regarded nuclear war as too dangerous to wage, a decision which manifested itself not so much in foreign policy or military doctrine but in his determination to avoid war when the possibility arose. We argue that Khrushchev’s experience provides us with a more useful way to characterise the nuclear revolution and suggest some implications of this argument for contemporary debates about nuclear weaponry.     

Classical geopolitics,realism and the balance of power theory

Since the end of World War II, classical geopolitics as a particular form of realism has been disengaged from the development of mainstream realist theories. This disengagement has not only concealed the value of classical geopolitics as a framework of analysis for policy and strategy, but also created an increasing rift between theory and policy in contemporary realist theories. This paper seeks to reengage classical geopolitics with mainstream realist theories by clarifying its realist traits and analytical characteristics, (re)stating its core propositions and probing into its potential contribution to the development of mainstream realist theories. This paper contends that classical geopolitics, while having a distinctive pedigree, can arguably be considered an integral part of the family of realist theories in view of its basic theoretical assumptions concerning international anarchy, the unit of analysis and power politics. As a framework of analysis, classical geopolitics incorporates three interrelated strategic propositions. Those three propositions not only constitute the theoretical core of classical geopolitics, but also manifest a peculiar balance-of-power conception that is essentially distinct from those proposed by mainstream realist theories. This paper argues that those three propositions combined promise to fill in prominent lacuna in the balance-of-power research programme, and also have significant implications for contemporary world politics.     

The Russian hybrid warfare strategy – neither Russian nor strategy

Following Russia’s annexation of Crimea and its initial actions in eastern Ukraine in 2014, the term hybrid warfare has received much public attention. Many have argued that the Russian actions we saw in Ukraine were part of a completely new strategy while others have suggested that there was nothing new in Russia’s actions. This article takes a critical look at these claims. Through the assessment of the history of the term hybrid warfare and a rigorous analysis of the so-called Gerasimov doctrine, this study finds that the Russian hybrid warfare strategy is rather a western myth than a formal comprehensive Russian strategic concept. Additionally, through the assessment of the Russian use of information operations and the way she has utilised the cyberspace in several recent conflicts, the study finds that against all claims Russia did not make these areas its main battlefield, but rather has been using them in support of its traditional concepts.

Robust adaptive UKF based on SVR for inertial based integrated navigation

Aiming at the problem that the traditional Unscented Kalman Filtering (UKF) algorithm can’t solve the problem that the measurement covariance matrix is unknown and the measured value contains outliers, this paper proposes a robust adaptive UKF algorithm based on Support Vector Regression (SVR). The algorithm combines the advantages of support vector regression with small samples, nonlinear learning ability and online estimation capability of adaptive algorithm based on innovation. Firstly, the SVR model is trained by using the innovation in the sliding window, and the new innovation is monitored. If the deviation between the estimated innovation and the measured innovation exceeds a given threshold, then measured innovation will be replaced by the predicted innovation, and then the processed innovation is used to calculate the measurement noise covariance matrix using the adaptive estimation algorithm. Simulation experiments and measured data experiments show that SVRUKF is significantly better than the traditional UKF, robust UKF and adaptive UKF algorithms for the case where the covariance matrix is unknown and the measured values have outliers.
