The focus now moves to DSA in military systems. Within military command and control systems, SA is a critical commodity (Artman, 2000; Riley et al., 2006) and is often a key factor that distinguishes between mission success and failure. The nature of military systems is such that studying DSA within them is likely to yield significant findings related to the advancement of DSA theory and measurement. Military systems are intrinsically complex and typically feature large teams of agents dispersed over large distances (sometimes even continents) working collaboratively in pursuit of common goals. Tasks are typically performed in complex, rapidly changing, and uncertain settings under time pressure and high-risk levels (Riley et al., 2006). To complicate things further, the military are typically working alongside coalition forces from other nations and other non-military groups such as non-government organisations (NGOs) and charities. Further, the groups are working against an enemy of some sort whose main goal is to defeat them.
