Major Stepan Stebelski of the Ukrainian Insurgent Army: examples of insurgency leadership and tactics

This is a biographical analysis of Stepan Stebelski (‘Khrin’) and his time in the Ukrainian Insurgent Army. His military command is an example of classic insurgency tactics and strategies. He was trained in underground tactics before the Second World War, used his image very effectively during his time in the UPA, and used his knowledge of the terrain to become an exceptional enemy against Soviet and Polish authorities.     

The vanguard's dilemma: understanding and exploiting insurgent strategies

The purpose of this paper is to provide a better conceptualization of insurgent strategies. Specifically, I shall examine Che Guevara's ‘Foco’ theory of insurgency, as it is one of the most theoretically popular and most pervasive strategies of insurgency currently practiced throughout the world. After briefly examining the origins, objectives, and theoretical strengths of the Foco theory (also known as the Vanguard Theory), I will argue that Guevara's theory suffers from an internal tension that I term the ‘Vanguard's Dilemma’. The significance of this dilemma creates a tension within the Vanguard Theory that can be fatal for insurgents if properly exploited by counterinsurgent operations. This paper will examine in detail this dilemma and show how it can be exploited. Given that several insurgent groups within Iraq and Afghanistan currently adhere to the Vanguard Theory of insurgency, a proper understanding of this insurgent strategy is an essential first step in the long road towards confronting and winning asymmetrical conflicts.     

The strategic utility of New Zealand Special Forces

In 1955, the New Zealand government authorised the creation of a Special Forces unit to operate with British forces in Malaya to counter a communist-inspired guerrilla insurgency. Drawing upon the operational experiences of the New Zealand SAS largely taken from the Cold War period, and underpinned by Colin Gray's Special Forces essentials of ‘economy of force’ and ‘expansion of choice’, this article will show how New Zealand's SAS is now accepted not only as a respected and relevant part of the nation's military capability, but also empowers its political decision-makers with the confidence to take on significant, and at times difficult, strategic foreign-policy choices.     

‘Taylor must go’ – the strategy of the Liberians United for Reconciliation and Democracy

In 1999, rebels rose to oppose the newly elected former warlord Charles Taylor in Liberia. Motivated by a variety of reasons, the minimal common denominator of these rebels, who assumed the name Liberians United for Reconciliation and Democracy (LURD), was that Charles Taylor must leave the country. The decentralized nature of LURD though stands out in their struggle, as they don't fit the unitary actor assumed by literature on strategy, nor the alternative conception of decentralized forces fighting for purely local reasons. Understanding such aberrations as LURD is the first step to finding strategies that can incorporate and manage them.     

一种基于节点资源利用率的无标度网络路由策略

本文研究了节点负载处理能力异质条件下的无标度网络交通动力学过程,提出了一种基于节点资源利用率的全局动态路由策略。该策略利用网络中节点资源利用率构建了一种全局代价函数,选择使该代价函数最小的路径来传输负载。实验结果表明该路由策略在略微增加平均路径长度的情况下成倍地提高了网络负载传输能力,与有效路由策略的比较进一步验证了该策略的有效性。

大型商业性建筑安全疏散策略研究

近年来,大型商业性建筑火灾事故时有发生,造成了重大损失,火灾发生时如何提高人员的疏散效率是降低伤亡率的要素.通过对大型商业性建筑火灾危险性和疏散中存在的问题进行分析,结合实际从设置消防救援窗,严格划分防火分区,合理设置疏散楼梯和安全出口,制定安全疏散预案,加强消防安全培训,充分利用声光报警等方面论述了优化大型商业性建筑人员疏散效率的策略.     

基于搜索论的远程反舰导弹搜捕概率建模方法

针对传统捕捉概率模型难以满足远程反舰导弹机动搜捕概率建模计算的问题,提出利用搜索论进行导弹机动搜捕概率计算的建模方法。该方法根据目标机动规律建立其分布概率密度函数,并依据末制导雷达发现目标概率的"倒四次方律"及弹目相对运动轨迹,构建其探测函数,通过求取两者之积的积分实现搜捕概率计算。计算结果显示:若远程反舰导弹不采取机动搜捕策略,目标指示误差增加1km时搜捕概率降低0.47,目标速度增加10节时搜捕概率降低0.3,末制导雷达搜索半径减小50%时搜捕概率降低0.3;若采取平行搜捕策略,上述因素对其影响大幅下降。可见,该方法综合考虑了目标机动规律、传感器探测规律、导弹搜捕策略,可实现远程反舰导弹机动搜捕概率的解算。
