Demobilisation,disarmament and reintegration in the Democratic Republic of Congo: The numbers game

Abstract

The creation of the Africa Command (AFRICOM) has reflected the growth in the strategic importance of Africa in US foreign policy since the end of the 1990s. One of the objectives of this new geographical military command is to forge closer links between foreign, security and development policies. However, this approach met with a number of difficulties associated with the challenge of ‘inter-agency cooperation’ among rather disparate actors from foreign affairs, defence and development. In addition, the establishment of AFRICOM has met with fierce criticism in the US and elsewhere – especially in Africa – culminating in the charge that the US foreign and development policies in Africa are being militarised. Although AFRICOM has a number of interesting features, this paper shows that it has reacted to these criticisms by realigning itself more closely with the traditional model of a military command, at the expense of the innovative interagency elements.

Local defence forces and counterinsurgency in Afghanistan: learning from the CIA's Village Defense Program in South Vietnam

Some scholars would have us believe that the distinctions between military and policing roles, methods and objectives have become increasingly blurred by the security demands of a post-Cold War and post-11 September global and domestic order. This article explores the current state of the police–military divide through a conceptual and case study analysis. It concludes that, in this case, there is some conflation occurring at a macro-level as international and domestic affairs have become increasingly indistinct, but the article also demonstrates that the actual ethos and practice of these agencies still differs strongly. Most importantly, the article argues that this distinction is in fact a very useful one in planning for future peace support operations     

UN-Consistent: A Comparison of Australia's Military Interventions in Somalia and Rwanda

This article seeks to compare Australia's involvement in two key 1990s peace missions: those to Somalia in 1992–93 and Rwanda in 1994–95. While there are many similarities between the two missions in terms of time, scale and theatre, the differences are more important. Both missions are usually recalled as failures despite the Australian troops having been extremely successful in their roles during both deployments. Moreover the experiences with intervention in Africa seem to have forever blighted Australian participation in peace missions on that continent.

箔条干扰条件下舰空导弹单发杀伤概率计算

目前,对导弹抗干扰能力的要求越来越高,干扰条件下的导弹单发命中概率已成为评定导弹性能的重要指标.针对箔条干扰条件下舰空导弹单发杀伤概率评定,建立了雷达导引头接收端信干比模型、舰空导弹圆目标落入概率模型以及抗干扰改善因子模型,从而构建了箔条干扰条件下舰空导弹单发命中概率模型,计算出真实有效的单发命中概率.     

地空导弹对地面的附带损伤问题研究

研究了地空导弹爆炸时战斗部破片对地面人员附带损伤的问题,选取了破片对人体的杀伤准则,通过分析破片的空中运动特性,对导弹战斗部爆炸时的破片飞散规律进行了探讨,建立了破片散布的数学模型,并在典型的给定计算条件下进行了仿真分析.仿真结果表明,地空导弹在不同高度爆炸时,可计算出对地面人员的有效杀伤破片数量、破片杀伤面积和平均密度以及导弹的安全高度.
