结合美国在近几年的几次局部战争中所使用的高科技的信息化武器装备、远程作战武器和精确打击武器等武器装备,研究分析了高科技武器装备的发展动态,促进产生了一些新的作战理念(战术战法、作战理论),如网络中心战、夺取制信息权、非对称作战和非线性作战,而新的作战理念又推动了高科技武器装备的完善和进一步发展。同时还分析了高科技武器装备目前尚存在的一些不足。 相似文献

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. 相似文献

Combat in near-Earth orbit is emerging as a more realistic possibility. The argument here is that changes in space technologies combined with a sea change in political rhetoric is bringing the possibility of military conflict in space technologies. This movement reflects a generational shift as the original decisions regarding military conflict in space are now being reassessed by a generation who did not experience World War II or the Cold War. For these, the sanctuary approach to space activities is not as persuasive and new enhanced space technologies bring the possibility of victory or at least survival possible during a conflict in space. 相似文献

Using a new set of data from Greek Army sources, US military archives, and Communist Party documents, the paper provides a quantitative analysis of the armed confrontation that took place in Greece during 1946–1949. A dynamic Lotka–Volterra model is estimated, pointing to the existence of a conflict trap that explains the prolongation of the civil war and its dire consequences for the country. A regional analysis finds that the mobilization of guerrilla forces was crucially affected by morphology and the local persecutions of political rivals. Using neoclassical growth-accounting, the economic cost of the conflict is estimated to surpass an annual GDP, in line with similar findings in contemporary civil wars. The same framework is employed to assess the outcome in counterfactual situations discussed in this paper. 相似文献

The article is devoted to problems of defining quantitative criteria for the physical protection system (PPS) effectiveness of nuclear facilities. The article briefly describes the scheme of the PPS development used in the nuclear industry in Russia, gives a review of existing approaches to defining the minimal acceptable value of the system's effectiveness, and reveals advantages and disadvantages of the approaches. The article describes in detail an approach based on facility categorization by potential losses and a technique of defining the minimal acceptable value of the PPS effectiveness developed on its base. 相似文献

According to just war theory, a resort to war is justified only if it satisfies the right intention condition. This article offers a critical examination of this condition, defending the thesis that, despite its venerable history as part of the just war tradition, it ought to be jettisoned. When properly understood, it turns out to be an unnecessary element of jus ad bellum, adding nothing essential to our assessments of the justice of armed conflict. 相似文献

Case summary, by James Cook (Case Study Editor):In the final issue of the 2015 volume of the Journal of Military Ethics, we published a case study entitled “Coining an Ethical Dilemma: The Impunity of Afghanistan’s Indigenous Security Forces”, written by Paul Lushenko. The study detailed two extra-judicial killings (EJKs) by Afghan National Police (ANP) personnel in an area stabilized and overseen by a US-led Combined Task Force (CTF). To deter further EJKs following the first incident, the CTF’s commander reported the incidents up his chain of command and used the limited tools at his disposal to influence local indigenous officials directly. Apparently, the ANP unit took no notice. In his commentary on the case study, Paul Robinson considered moral compromise in war more generally. Coalition troops in Afghanistan, for instance, have encountered not just EJKs but also sexual abuse of minors, killing of non-combatants, kidnapping, torture, and widespread corruption. What should the soldier on the ground do if indigenous personnel violate Laws of Armed Conflict (LOAC) with impunity? Refusing to serve will not right or prevent moral wrongs, while staying on to fight the good but futile fight will mire the soldier in moral compromise. “?… [S]oldiers faced with this dilemma have no good options. The systemic failings surrounding them mean that it is probable that nothing they do will help”. In a concluding note, I suggested that while an individual soldier may indeed have no good options, as Paul Robinson suggests, that soldier’s military and nation at large are obliged to do what they can. At least, they must keep to the moral high ground so as not to give indigenous security forces an excuse to misbehave, and determine the nature of crimes such as EJKs: are they outlaw acts or in fact endorsed by the indigenous culture and perhaps even government? Below Colonel Dave Barnes, himself a veteran of Operation Enduring Freedom, analyzes Paul Lushenko’s case study at “?…?the local, tactical level: If a commander is in this situation – where her unit witnesses an EJK or other war crime – what should she do?” 相似文献
