Revisiting the rise and fall of the Somali Armed Forces, 1960–2012

The history of the Somali Armed Forces, principally the army, forms an important part of studying the Somali civil war. Two key themes are evident from 1960: the pursuit of an irredentist agenda beyond reasonable limits, which led to the downfall of Siad Barre’s regime, and the clan divisions and agendas that Barre used to shore up his rule in the 1980s and that have bedeviled the rebirth of the Somali Army in the twenty-first century. With the twentieth-century context covered, and in some places reinterpreted, this article then focuses on the uncertain rebirth of the Somali Armed Forces since 2008, using a host of primary and United Nations official sources. Assistance efforts have been focused on Mogadishu, but limited success has been made in forming truly national armed forces. Future prospects are uncertain, but there are some signs of hope.     

The impotence of conventional arms control: why do international regimes fail when they are most needed?

Amid tensions with the West over Ukraine, Russia pulled out of the Treaty on Conventional Armed Forces in Europe in March 2015. The Russian case is another example of a country disengaging from conventional arms control when relations with other member states deteriorate. This raises an important question: can arms control regimes aimed at preventing conflict survive periods of tension and preserve peace? This article argues no. It demonstrates that the prospect and stability of conventional arms control regimes depend on healthy international relations. In times of tension, governments rely on military institutions for advice and absorb military biases incompatible with arms control. Therefore, these regimes fail when most needed and are impotent as instruments of peace. Beyond conventional arms control, the article hints at the fragility of nuclear agreements such as the 2015 Iran deal and the 2010 New START between the United States and Russia.     

Optimal job splitting on a multi‐slot machine with applications in the printing industry

In this article, we define a scheduling/packing problem called the Job Splitting Problem, motivated by the practices in the printing industry. There are n types of items to be produced on an m‐slot machine. A particular assignment of the types to the slots is called a “run” configuration and requires a setup cost. Once a run begins, the production continues according to that configuration and the “length” of the run represents the quantity produced in each slot during that run. For each unit of production in excess of demand, there is a waste cost. Our goal is to construct a production plan, i.e., a set of runs, such that the total setup and waste cost is minimized. We show that the problem is strongly NP‐hard and propose two integer programming formulations, several preprocessing steps, and two heuristics. We also provide a worst‐case bound for one of the heuristics. Extensive tests on real‐world and randomly generated instances show that the heuristics are both fast and effective, finding near‐optimal solutions. © 2010 Wiley Periodicals, Inc.

An Unlikely Alliance: Portuguese and South African Airpower in Angola, 1968–1974

The war that Portugal was obliged to fight in Africa began in 1961 and immediately stretched the resources of its armed forces. Nowhere was this thinness more apparent than in policing the vast territory of Angola. The east and southeast of Angola were particularly vulnerable, as the area was a vast, sparsely populated region characterised by enormous featureless plains or chanas covered in tall grass and broken by an extensive river system and mountainous forests. The only military solution to policing these immense spaces was aviation and specifically the helicopter that could carry troops into battle, protect them with a gunship and bring them home when the operation was concluded. The immediate problem for the Portuguese Air Force (Força Aérea Portuguesa or FAP) in Angola and elsewhere was a scarcity of helicopters. The solution was an alliance with South Africa, which had a strong inventory of Alouette IIIs, to help in policing the east. This move was likewise in the interest of South Africa, as its threat came from Zambia through south-eastern Angola. This article examines the strategic and tactical development of this unusual, cross-cultural alliance and the symbiotic relationship that resulted in destruction of the enemies of both in Angola.     

How might Democratisation Affect Military Professionalism in Africa? Reviewing the Literature

The search continues for methods to improve security for development in Sub-Saharan Africa. One of the important actors in this security arena is Sub-Saharan African governments’ armies. Much of their capability to meet security challenge depends on how militarily professional they are. The wave of democratic evolution in Africa since 1990 also affected military professionalism. This article reviews three models for assessing how democratisation might affect military professionalism in Sub-Saharan Africa, with special attention to post-conflict states. This should make it possible to decide which analytical methods are most appropriate to measure military professionalism in the particular circumstances of Sub-Saharan African post-conflict democratisation. Depending upon the particular nation-state in question, this decision on analytical methods may be useful for other Sub-Saharan states as well.     

Terrorism, Crime and Private Armies

The nature of crime and conflict is rapidly evolving. Postmodern war is increasingly influenced by non-traditional and irregular combatants: non-state soldiers. These actors are exploiting technology and networked doctrine to spread their influence across traditional geographic boundaries. This emphasis on non-traditional actors accompanies a shift in political and social organization. This shift may well be a shift in state form: from nation-state to market-state. This transition is fueled by rapid developments in technology and the adoption of network organizational forms. Conflict during this transition blurs the distinctions between and among crime, terrorism and warfare. This essay explores the dynamics of terrorism, crime and private armies during this epochal shift.     

Transient solution of a finite-capacity M/Ga,b/1 queueing system

In this article we consider a single-server, bulk-service queueing system in which the waiting room is of finite capacity. Arrival process is Poisson and all the arrivals taking place when the waiting room is full are lost. The service times are generally distributed independent random variables and the distribution is depending on the batch size being served. Using renewal theory, we derive the time-dependent solution for the system-size probabilities at arbitrary time points. Also we give expressions for the distribution of virtual waiting time in the queue at any time t.     

Entropy-based selection with multiple objectives

In this article we present an approach to determine the initially unspecified weights in an additive measurable multiattribute value function. We formulate and solve a series of nonlinear programming problems which (1) incorporate whatever partial information concerning the attribute weights or overall relative value of alternatives the decision maker chooses to provide, yet (2) yield a specific set of weights as a result. Although each formulation is rather easily solved using the nonlinear programming software GINO (general interactive optimizer), solutions in closed form dependent on a single parameter are also provided for a number of these problems.     

Moving Beyond Population-Centric vs. Enemy-Centric Counterinsurgency

Historically, insurgency is one of the most prevalent forms of armed conflict and it is likely to remain common in the foreseeable future. Recent experiences with counterinsurgency in Iraq and Afghanistan offer many lessons for future counterinsurgents, but the discourse on the subject continues to be mired in a traditional dichotomy pitting population-centric approaches to counterinsurgency against enemy-centric approaches. Historical analysis suggests that this traditional dichotomy is not a sufficiently nuanced way to understand or plan for such operations. Instead, discussions of counterinsurgency should focus on two dimensions: actions (use of physical force vs. political or moral actions) and targets (active insurgents vs. insurgent support). This perspective divides the space of possible counterinsurgency efforts into four quadrants, suggesting that effective counterinsurgency campaigns find a balance of effort across the four quadrants that is well matched to the specific context.
