Modern defence forces rely mainly on intelligent information systems and high technology armour. This volume reflects the latest trends in military information systems research by bringing together international contributions that span communications technology, intelligent agents and large-scale modelling and simulation, and sociotechnical systems. Together, the articles represent a cross-section of contemporary information systems research. The text also shows the wealth of research on advanced information systems and on technologies developed for defence purposes. Some of the chapters may serve as a component of advanced defence training programmes. They provide an important overview of crucial research, which has evolved since the 1990s.
