Abstract
Efficient communication is essential to effective team coordination. In particu- lar, the use of specialized military terms with specific meanings is essential to accurate communications and also helps keep messages short. Internal Combat Information Center communications were recorded during Navy team training. Communication behavior was classified by speech turns, with emphasis on the use of military terms. Even though the purpose of military terms is to promote brevity and accuracy, speech turns with military terms were wordier and had more format violations than did those without military terms. Military terms were used as officially defined only 57% of the time, and little change was found over training. Subjective comments made during debriefing sessions did not reflect actual measured behavior. The results suggest areas of communica- tion behavior where specific training might be useful, including the accurate use of military terms.
