This report describes a three-day experiment investigating input and display devices for voice communications in the context of urban section attacks. Four input/display pairs were investigated: 1) a boom microphone input device combined with an open ear speaker display, 2) an in-ear bone-conduction input device and an in-ear bone-conduction speaker display, 3) a throat microphone input device combined with a helmet-mounted speaker display and 4) a cranial bone-conduction input device with a cheek bone-conduction speaker display. The aims of the experiment were to compare the effectiveness of different input and display devices for radio communication and to identify the optimum input/display combination for intra-section infantry radios. Sixteen soldiers organized into two sections were participants in the experiment. The participants completed a series of section attacks against three enemy force soldiers in an urban environment, while communicating using each of the four systems under investigation. Each participant used each configuration twice for a total of eight section attacks per participant. Data collection included questionnaires, focus groups and HF observer assessments. Questionnaire data was collected in nine categories: Information Transfer, Mission Coordination, Fit and Comfort, Situation Awareness, Compatibility, Function, Durability, Reliability and Overall Evaluation. The data collected from the questionnaires indicated a preference for the cranial bone-con
