The upsurge in post-Cold War coalition operations has stimulated research on caveats: national reservations on the use of force in multinational military operations. However, because the concept of caveats has no agreed-upon definition, it is used inconsistently. This in turn impedes comparing research findings across academic and policy studies and therefore systematic research. This article is a contribution to the scholarly debate on how the analytical concept of caveats are to be delimited. Crucially, we argue that caveats result from some calculated political decision, and should not be confused with reserved behavior due to financial and technical limitations, or lack of coordination. We suggest that caveats are empirically observed and measured in two ways: First, we argue that coalition rules of engagement should be used as a yardstick for measuring direct reservations on the use of force. Second, we suggest reservations on task-assignment and geographical mobility should be used to register indirect reservations.  相似文献

ABSTRACT

This article examines the strategic purpose of Individual Augmentee Officers (IAOs) for junior partners in multinational military operations through an exploratory case study of Danish IAOs in Iraq and South Sudan between 2014 and 2017. IAOs are individual officers who are moved from their normal functions to be seconded to other units of the armed forces of their own or another country or an international institution. The study concludes that IAOs function as strategically important, yet not necessarily indispensable, supplements to military contingents in several ways: making tangible contributions to the overall mission (contributing), gaining access to information, knowledge, and experience (learning), and lobbying decision-making processes within mission headquarters (lobbying). The usefulness of IAOs depends on whether the junior partner has specific interests and a significant presence in the theatre and whether the mission is conducted as a UN mission, a NATO mission, or an ad hoc coalition.  相似文献

Hybrid warfare is the latest of the terms/concepts that have been used within the defence community in the last three decades to label contemporary warfare. It has been officially adopted in the core strategic documents of NATO, EU and national governments and has already inspired many articles, policy papers and books; however, this paper is unique in the sense that it analysis the hybrid warfare concept through the lens of strategic theory. It is argued that hybrid warfare does not merit the adoption as a doctrinal concept. Strategic theory instead, which lies at the nexus of all dimensions of warfare, provides a better viewpoint to approach contemporary warfare. It concludes that efforts should be directed towards exploring warfare under the light of eternal principles instead of proving the emergence of new types of warfare.  相似文献

In the late 1990s and 2000s, a slew of books and journal articles proposed that a nexus between risk management and warfare was emerging. This article argues that risk management ideas continue to shape recent campaigns against Libya, Islamic State, Syria, and the war on terror from Niger, Yemen to Somalia. It uses existing literature on risk and warfare to examine four key aspects of contemporary interventions. First, the article evaluates the overall strategic context as security concerns shift from terrorism toward renewed great power competition. Second, it re-assesses the risk calculus for military action through the language and grammar of risk invoked by politicians. Third and fourth, it addresses the continuing reliance on air power and the managerial ethos of military operations as important features of war as risk management.  相似文献

Why do states make substantial military contributions to coalition operations, while at the same time apply reservations, or caveats, to how the coalition can use the military contributions? Caveats rose to prominence in defense and policy circles with NATO’s campaign in Afghanistan. In the scholarly security literature, the term remains a buzzword for all types of reserved efforts by states in coalition warfare, but there are few theoretical accounts addressing caveats. This article contributes to the knowledge gap on caveats through a comparative case study of Denmark’s, the Netherlands’, and Norway’s contributions to NATO’s intervention in Libya in 2011. It demonstrates that caveats can occur through three different causal pathways: compromises from domestic bargaining, handling of alliance commitments, and implementation and civil–military relations. Insights into the complexity that causes caveats are highly relevant for both political and military decision-makers that are trying to coordinate states’ effort in coalition operations.  相似文献

The term “Gray Zone” is gaining in popularity as a way of describing contemporary security challenges. This article describes the “short-of-war” strategies – the fait accompli, proxy warfare, and the exploitation of ambiguous deterrence situations, i.e. “salami tactics” – that are captured by the term and offers several explanations for why state and non-state actors are drawn to these strategies. The analysis highlights why defense postures based on deterrence are especially vulnerable to the short-of-war strategies that populate the “Gray Zone.” The article concludes by suggesting how defense officials might adapt defense policies to life in the “Gray Zone.”  相似文献

The paper presents the possibilities of, and methods for, acquiring, analysing and processing optical signals in order to recognise, identify and counteract threats on the contemporary battleground. The main ways electronic warfare is waged in the optical band of the electromagnetic wave spectrum have been formulated, including the acquisition of optical emitter signatures, as well as ultraviolet (UV) and thermal (IR) signatures. The physical parameters and values describing the emission of laser radiation are discussed, including their importance in terms of creating optical signatures. Moreover, it has been shown that in the transformation of optical signals into signatures, only their spectral and temporal parameters can be applied. This was confirmed in experimental part of the paper, which includes our own measurements of spectral and temporal emission characteristics for three types of binocular laser rangefinders. It has been further shown that through simple registration and quick analysis involving comparison of emission time parameters in the case of UV signatures in “solar-blind” band, various events can be identified quickly and faultlessly. The same is true for IR signatures, where the amplitudes of the recorded signal for several wavelengths are compared. This was confirmed experimentally for UV signatures by registering and then analyzing signals from several events during military exercises at a training ground, namely Rocket Propelled Grenade (RPG) launches and explosions after hitting targets, trinitrotoluene (TNT) explosions, firing armour-piercing, fin-stabilised, discarding sabots (APFSDS) or high explosive (HE) projectiles. The final section describes a proposed model database of emitters, created as a result of analysing and transforming the recorded signals into optical signatures.  相似文献
