Information and the Air Defence Revolution, 1917–40

The Royal Air Force was successful in the Battle of Britain because of the elaborate and sophisticated air defence system of Fighter Command. This system had its foundations in the early warnings which radar provided. The process of collecting a huge amount of often inaccurate and contradictory data from radar stations, and then turning it into useful information which could direct fighters to their targets was a remarkable accomplishment. Information was the key to this revolution in military organisation, command and control procedures, and tactics. The origins of this information revolution predate radar, and can be traced back to World War I.     

The virtual dimension of contemporary insurgency and counterinsurgency

This paper looks at the virtual dimension of contemporary insurgency and counterinsurgency. It argues that the West is faltering in the ‘War of Ideas’ with global Jihad for the main reason that the messages that we wish to convey lack narrative coherence. This is a result of the fact that we misapprehend the nature of the virtual operational environment whereas our opponents possess an intuitive grasp of it as a result of which their structure and method of operations are better adapted and more effective than our own. There is no reason, beyond inertia, that this should remain the case.

‘A Particularly exacting operation’: British Forces and the Battle of Surabaya,November 1945

In 1945, the Dutch government was not in a position to re‐impose its control upon its colonies in the East Indies after the surrender of Japan. In their stead, Allied forces were to take control of the islands, disarm Japanese troops and to maintain stability until the Dutch could return. The declaration of an independent Indonesia by nationalists left the British and Indian troops sent to re‐occupy the islands facing a complex situation. Increasing violence culminated in the murder of Brigadier A.W. S. Mallaby in Surabaya, which was followed by a major action by British forces to regain control. In extremely difficult circumstances, the British troops conducted a successful operation which held many lessons for the conduct of counter‐insurgency operations in the years that followed.     

United States special operations forces and the war on terrorism

Those leading the war on terrorism have emphasized from the beginning that this war would be unlike other wars. Special Operations Forces (SOF) are military forces unlike other military forces. The implication is that SOF and the war on terrorism are thus made for each other. This contribution examines this assumption, the war on terrorism and SOF in greater detail.     

Comparison between constant‐stress and step‐stress accelerated life tests under Time Constraint

By running life tests at higher stress levels than normal operating conditions, accelerated life testing (ALT) quickly yields information on the lifetime distribution of a test unit. The lifetime at the design stress is then estimated through extrapolation using a regression model. In constant‐stress testing, a unit is tested at a fixed stress level until failure or the termination time point of test, whereas step‐stress testing allows the experimenter to gradually increase the stress levels at some prefixed time points during the test. In this work, the optimal k‐level constant‐stress and step‐stress ALTs are compared for the exponential failure data under complete sampling and Type‐I censoring. The objective is to quantify the advantage of using the step‐stress testing relative to the constant‐stress one. Assuming a log‐linear life–stress relationship with the cumulative exposure model for the effect of changing stress in step‐stress testing, the optimal design points are determined under C/D/A‐optimality criteria. The efficiency of step‐stress testing to constant‐stress one is then discussed in terms of the ratio of optimal objective functions based on the information matrix. © 2013 Wiley Periodicals, Inc.

Myth and the small war tradition: Reassessing the discourse of British counter-insurgency

In recent years a number of commentators have posited that the British reputation for conducting small wars has suffered in the wake of setbacks in Iraq and Afghanistan. The argument here contests whether such a tradition can be truly said to have ever existed. A close examination of this supposed tradition reveals it to be a myth. In fact, rarely have the British armed forces claimed a facility for counter-insurgency or small war. Invariably, commentators outside the Army have ascribed the tradition to them. Most notably, commentators in the United States keen to discern practices of minimum force or rapid institutional learning generated the narrative of British COIN expertise. Ultimately, what this myth reveals is that, when deconstructed, it is political will, not an ingrained understanding of fighting insurgencies, that has determined Britain's success, or otherwise, in so-called small wars.
