Abstract: This paper considers a number of themes, and seeks to show that they should be considered jointly rather than severally. First the historical aspect of technology is considered as applied to data transmission, particularly for command and control (C2) data. Next, the paper discusses a standard language for modelling command and control in combat situations, and how this could be extended from use in synthetic environments to the modern network-enabled forces. It is argued that a command or battlespace modelling language intended to ensure compatibility between simulation platforms can be developed for practical use in the modern digitized force. The object of this would be to minimise the 'display fixation' which has already been shown to occur with battle management displays. The paper then considers C2 messaging in the fields of civil aviation and ground combat and considers lessons learned on the effect of changes in aircrew workload and behaviours brought about by the use of data link displays for message transmission. The paper concludes that modern battlefield command systems can potentially be improved by the use of techniques borrowed from other domains.
