Abstract: The impending advent of digitisation has fuelled interest in all components of military command and control (C2) and there is growing awareness of the importance of human issues relative to C2. A number of human behavioural aspects (such as individual and team decision processes, shared situational awareness, management of information) significantly impact upon the effectiveness of C2 but are, at present, poorly understood. This paper discusses these human aspects of C2 in some detail, assesses their relative impact, and presents a simple model of the interaction between the information, infrastructure and intangible issues associated within a command post.
