Optimizing the US Navy's combat logistics force

We study how changes to the composition and employment of the US Navy combat logistic force (CLF) influence our ability to supply our navy worldwide. The CLF consists of about 30 special transport ships that carry ship and aircraft fuel, ordnance, dry stores, and food, and deliver these to client combatant ships underway, making it possible for our naval forces to operate at sea for extended periods. We have modeled CLF operations to evaluate a number of transforming initiatives that simplify its operation while supporting an even larger number of client ships for a greater variety of missions. Our input is an employment schedule for navy battle groups of ships operating worldwide, extending over a planning horizon of 90–180 days. We show how we use optimization to advise how to sustain these ships. We have used this model to evaluate new CLF ship designs, advise what number of ships in a new ship class would be needed, test concepts for forward at‐sea logistics bases in lieu of conventional ports, demonstrate the effects of changes to operating policy, and generally try to show whether and how the CLF can support planned naval operations.

A generalized model for estimation of aerodynamic forces and moments for irregularly shaped bodies

A novel method for estimation of an aerodynamic force and moment acting on an irregularly shaped body (such as HE projectile fragments) during its flight through the atmosphere is presented. The model assumes that fragments can be approximated with a tri-axial ellipsoid that has continuous surface given as a mathematical function. The model was validated with CFD data for a tri-axial ellipsoid and verified using CFD data on aerodynamic forces and moments acting on an irregularly shaped fragment.The contribution of this method is that it represents a significant step toward a modeling that does not require a cumbersome CFD simulation results for estimation of fragment dynamic and kinematic parameters. Due to this advantage, the model can predict the fragment motion consuming a negligible time when compared to the corresponding time consumed by CFD simulations. Parametric representation (generalization) of the fragment geometrical data and the conditions provides the way to analyze various correlations and how parameters influence the dynamics of the fragment flight.

British operations among the people and civilian risk

ABSTRACT

Debates on military intervention and small wars often include the claim that soldiers should operate among civilians in order to avoid civilian casualties and to protect civilians against third-party violence. This article, by contrast, points at negative unintended consequences of military operations taking place in close proximity to local populations: it argues that also risk-tolerant militaries cause civilian casualties and that their presence triggers third-party violence against civilians. The British military, in particular the British Army, exported risk-tolerant practices from Northern Ireland to the Balkans, with sporadic success. But in southern Iraq and in Helmand, British ground operations harmed civilians. The findings suggest that the chances for protection are better in operations where levels of violence are relatively low than in counterinsurgency where troops face ruthless and well-endowed enemies operating among civilians.     

‘Troops were then forced to fire’: British army crowd control in Palestine,November 1945

In November 1945, British army shooting during street riots and search operations in Palestine resulted in the death of 13 Jews and the injuring of dozens. The most costly in casualties caused by army fire during the whole Jewish insurgency, these incidents have nevertheless not received detailed attention in literature on the British army's counterinsurgency campaign in postwar Palestine. This article outlines British military use of firepower to control civilian crowds and the difficulties involved during these incidents, contributing to the debate on the army's principal of ‘minimum force’. It also highlights the serious problem of legitimizing opening of fire on unarmed protestors, epitomized in the army's fabricated account justifying shooting at a large crowd rushing a military cordon at Givat Hayim.     

The concept of logistics derived from Clausewitz: All that is required so that the fighting force can be taken as a given

This article assesses the existing literature on logistics in war, concluding that there is no satisfactory conceptual definition of logistics. It proposes a concept of logistics derived from Clausewitz's theory of war to fill that void. This is presented as a derivation because Clausewitz's distinction between (1) the use of the fighting forces (tactics and strategy) and (2) all other activities in war that were required so that forces could be taken as a given. The latter, left unnamed by Clausewitz, corresponds to a concept of logistics that proves to be an analytical peer to Clausewitz's categories of politics, tactics and strategy.     

General Dostum and the Mazar i Sharif Campaign: new light on the role of Northern Alliance warlords in Operation Enduring Freedom

This report sheds new light on the CIA and US Special Forces' covert campaign alongside Afghan Northern Alliance leader General Dostum's horse-mounted Uzbeks during 2001's Operation Enduring Freedom. In 2003 and 2005 the author traveled over the Hindu Kush Mountains to the plains of Northern Afghanistan and lived with the legendary Northern Alliance opposition leader General Dostum. His aim was to recreate Dostum's campaign alongside the CIA and Special Forces to seize the holy city of Mazar i Sharif from the Taliban in November 2001. Based on interviews with Dostum and his Uzbek commanders, this article recreates this proxy offensive that saw the Northern Alliance opposition break out of the mountains, seize this shrine town and bring the Taliban house of cards falling down in a matter of weeks. Up until now the indigenous Afghan Uzbeks, who played a crucial role as a ‘boots on the ground’ fighting force for Centcom, have been cast as a mere backdrop for American heroics. Now their side of the story and their links to the mysterious shrine of Mazar i Sharif are for the first time revealed.
