1. Introduction
1.1 Human Factors Problems In Military Command Teams
Over recent years, there has been an increasing focus on the human component of
military Command and Control (C2). A variety of tragedies have demonstrated that
one of the largest influences on system performance is the human factor. Human
error has been found to be responsible for 60% to 80% of fatal aviation accidents, and
communication issues were found to be involved in more than 70% of accidents
(Brannick, Prince, Prince & Salas, 1995). The suggestion is that a large influence on
effective performance is the way humans interact with each other. Thus, a critical
determinant of performance is the team behaviour.
Nowhere was this influence seen so strongly as in the USS Vincennes incident. In
1988, the Commanding Officer (CO) of the Vincennes fired two SM-2 missiles at a
civilian Iranian airbus leaving no survivors (Gregory & Kelly, 1998). The CO made
his decision to engage based on information he received from crew members in the
Combat Information Centre (Klein, 1993). What is noteworthy is that all equipment
on the Vincennes (except the forward gun) worked impeccably throughout the
incident. Likewise, the information needed to prevent the tragedy was readily
available to the crew.
This incident sparked a congressionally mandated research project, and it has been
suggested that the dynamics of the command team were the cause of the tragedy. In
particular, the extent to which the team dynamics influenced the interpretation of the
