British operations among the people and civilian risk

ABSTRACT

Debates on military intervention and small wars often include the claim that soldiers should operate among civilians in order to avoid civilian casualties and to protect civilians against third-party violence. This article, by contrast, points at negative unintended consequences of military operations taking place in close proximity to local populations: it argues that also risk-tolerant militaries cause civilian casualties and that their presence triggers third-party violence against civilians. The British military, in particular the British Army, exported risk-tolerant practices from Northern Ireland to the Balkans, with sporadic success. But in southern Iraq and in Helmand, British ground operations harmed civilians. The findings suggest that the chances for protection are better in operations where levels of violence are relatively low than in counterinsurgency where troops face ruthless and well-endowed enemies operating among civilians.     

‘Troops were then forced to fire’: British army crowd control in Palestine,November 1945

In November 1945, British army shooting during street riots and search operations in Palestine resulted in the death of 13 Jews and the injuring of dozens. The most costly in casualties caused by army fire during the whole Jewish insurgency, these incidents have nevertheless not received detailed attention in literature on the British army's counterinsurgency campaign in postwar Palestine. This article outlines British military use of firepower to control civilian crowds and the difficulties involved during these incidents, contributing to the debate on the army's principal of ‘minimum force’. It also highlights the serious problem of legitimizing opening of fire on unarmed protestors, epitomized in the army's fabricated account justifying shooting at a large crowd rushing a military cordon at Givat Hayim.     

The concept of logistics derived from Clausewitz: All that is required so that the fighting force can be taken as a given

This article assesses the existing literature on logistics in war, concluding that there is no satisfactory conceptual definition of logistics. It proposes a concept of logistics derived from Clausewitz's theory of war to fill that void. This is presented as a derivation because Clausewitz's distinction between (1) the use of the fighting forces (tactics and strategy) and (2) all other activities in war that were required so that forces could be taken as a given. The latter, left unnamed by Clausewitz, corresponds to a concept of logistics that proves to be an analytical peer to Clausewitz's categories of politics, tactics and strategy.     

General Dostum and the Mazar i Sharif Campaign: new light on the role of Northern Alliance warlords in Operation Enduring Freedom

This report sheds new light on the CIA and US Special Forces' covert campaign alongside Afghan Northern Alliance leader General Dostum's horse-mounted Uzbeks during 2001's Operation Enduring Freedom. In 2003 and 2005 the author traveled over the Hindu Kush Mountains to the plains of Northern Afghanistan and lived with the legendary Northern Alliance opposition leader General Dostum. His aim was to recreate Dostum's campaign alongside the CIA and Special Forces to seize the holy city of Mazar i Sharif from the Taliban in November 2001. Based on interviews with Dostum and his Uzbek commanders, this article recreates this proxy offensive that saw the Northern Alliance opposition break out of the mountains, seize this shrine town and bring the Taliban house of cards falling down in a matter of weeks. Up until now the indigenous Afghan Uzbeks, who played a crucial role as a ‘boots on the ground’ fighting force for Centcom, have been cast as a mere backdrop for American heroics. Now their side of the story and their links to the mysterious shrine of Mazar i Sharif are for the first time revealed.     

The Amritsar Massacre and the minimum force debate

This article re-examines one of the most infamous incidents in British imperial history: the Amritsar Massacre of 1919, and analyses it within the context of the British Army's minimum force philosophy. The massacre has long been regarded as the most catastrophic failure of minimum force in the history of the British Army. This article reconsiders the arguments over the shooting at Amritsar and the role of Brigadier-General Reginald Dyer, and questions the accepted view that the massacre was such a failure of minimum force. It argues that the circumstances surrounding the massacre must be understood before judging the incident and given these factors it is possible to see it within a minimum force framework.     

高超声速流动计算中LU-SGS隐式算法的应用

在高超声速条件下,对原始LU-SGS格式及其改进方法的收敛速度做了深入的比较分析,目的是进一步更好地将LU-SGS算法用于工程上复杂外形的计算模拟中。二维圆柱,三维钝锥及空天飞机算例的结果表明:对于高超声速粘性流动的计算,粘性项应进行隐式处理;BLU-SGS方法给出的内迭代方式的收敛性优于DP-LUR方法所给出的内迭代方式;LU-SGS算法中雅克比系数矩阵的计算方式对计算量及收敛性影响较大,若采用精确的矩阵形式,则在流动无分离情况下能取得快速收敛的效果,而在含有流动分离的情况,因受稳定性的影响,精确的矩阵形式的收敛表现不及对角近似形式。     

Alternatives for defense in the Post‐Soviet World: A guide for economists to the U.S. debate

The defense establishments of all major powers are changing to reflect changes in the foundations of national security strategy and resource allocation. The authors believe economists should play an active role in formulating these changes and offer an orientation to the U.S. debate, presenting three major alternatives: the “Base Force” (Bush Administration), Mr. Aspin's Force “C,” and the “Low” Alternative (Prof. Kaufmann and Dr. Steinbruner). These alternatives are compared using first‐order measures of capabilities, budgets and risk. Budgetary estimates are based on newly‐developed analytical tools.     

Specialization in defence forces

The choice between balanced and specialized defence forces depends on the technology of defence output (e.g. whether a force scope multiplier is present), the existence of scope and scale economies, the platform customization costs and, of course, the level of defence budgets. Minimum force element levels (thresholds), and scale economies facilitate specialization as opposed to scope economies (e.g. platform‐sharing), scale diseconomies and the force scope multiplier (e.g. defence weakest‐link technology). When a balanced force is not optimal, the option value of a non‐optimally maintained force element must also include the opportunity cost arising from suboptimal force elements. Shrinking defence budgets may produce two surprising phenomena. If some force elements are shut down as a result of thresholds, the surviving ones may increase in platform numbers as well as enjoying closer‐to‐most‐desirable platforms. Furthermore, if heritage force elements are shut down within the budget contraction environment, overall defence capability might rise.
