Group cohesion is very basic to the human condition and derived from the most fundamental nature of humans as found in the terminology of I am, I go, and I do. Group cohesion is found in the relationships of group members and their perceived capacity for joint action to achieve their missions. For some time the construct of task cohesion has been incorrectly or ambiguously included in the conceptualization of group cohesion. However, task cohesion, if used at all in the context of military group cohesion, should be considered part of the set of performance criteria as in cohesive task performance rather than as part of the cohesion predictor space. The author requests future researchers adopt this preferred word usage.
