Typically weapon systems have an inherent systematic error and a random error for each round, centered around its mean point of impact. The systematic error is common to all aimings. Assume such a system for which there is a preassigned amount of ammunition of n rounds to engage a given target simultaneously, and which is capable of administering their fire with individual aiming points (allowing “offsets”). The objective is to determine the best aiming points for the system so as to maximize the probability of hitting the target by at least one of the n rounds. In this paper we focus on the special case where the target is linear (one‐dimensional) and there are no random errors. We prove that as long as the aiming error is symmetrically distributed and possesses one mode at zero, the optimal aiming is independent of the particular error distribution, and we specify the optimal aiming points. Possible extensions are further discussed, as well as civilian applications in manufacturing, radio‐electronics, and detection. © 1999 John Wiley & Sons, Inc.

After 15 years of war in Afghanistan and Iraq, many now see ‘small-footprint’ security force assistance (SFA) – training, advising and equipping allied militaries – as an alternative to large US ground-force commitments. Yet, its actual military efficacy has been little studied. This paper seeks to fill this gap. We find important limitations on SFA’s military utility, stemming from agency problems arising from systematic interest misalignment between the US and its typical partners. SFA’s achievable upper bound is modest and attainable only if US policy is intrusive and conditional, which it rarely is. For SFA, small footprints will usually mean small payoffs.  相似文献

In clinical circles, the concept of “moral injury” has rapidly gained traction. Yet, from a moral philosophical point of view the concept is less clear than is suggested. That is, in current conceptualizations of moral injury, trauma’s moral dimension seems to be understood in a rather mechanistic and individualized manner. This article makes a start in developing an adequately founded conceptualization of the role of morality in deployment-related distress. It does so by reviewing and synthesizing insights from different disciplines into morality and trauma. This discussion will lead to three positions: (1) values and norms are by definition characterized by conflict, (2) moral conflict may entail important social dimensions, and (3) moral conflict may lead to altered beliefs about previously held values. These insights provide important steps in further developing conceptions of the role of morality in deployment-related suffering.  相似文献

The post-communist countries transition from the Warsaw Pact style of platforms and systems to Western-compatible capabilities has never been an easy task or a process without conflicts. This was no different for the Visegrád countries either, in which case the Hungarian Gripen procurement stands out. After much debate, Budapest decided to modernize its fighter fleet with the not battle tested Swedish-made Gripen fighter aircraft. This decision received several critiques due to the lack of transparency in the selection process and the initial lack of NATO-required systems. Subsequently, the fleet has had to operate in a financially demanding environment. Moreover, the air force has lost two aircrafts in accidents. Now that the jets are in the middle of their envisaged life cycle, it is more than appropriate to answer the question if the Gripens can utilize their full combat potential or will they fail the test of time?  相似文献

ABSTRACT

The United States has provided substantial amounts of military assistance and aid since the end of World War Two. During the Cold War, it proved vital in protecting numerous regimes from communist takeovers. Successful outcomes occurred when American leaders made large initial aid commitments, and the states had the capacity and political willpower to use it effectively. However, Vietnam was an example of how U.S. support lagged, as leaders in Saigon preferred political survival instead of creating regime legitimacy. Following 9/11, American security aid focused on making weak countries develop stronger security forces. Unfortunately, this created Fabergé egg militaries: expensive and easily broken by insurgents. This article suggests long-term strategic commitments need to be made alongside more resources for the American State Department and similar organizations to focus on the politics of state-building. Finally, this article suggests strategies, such as “whole-of-government” approaches, to improve long-term security and political institution building.  相似文献
