Soldiers in military tactical vehicles perform increasingly diverse tasks, including communication and weapons system control. Personal protective equipment (PPE) and body borne gear (BBG) restrict the soldier’s mobility and performance. This study is to quantify the effects of PPE and BBG and their interactions with a seat harness restraint system on seated maximal reach capability. Participants performed a series of maximal reaches, which were recorded using a motion capture system. The results showed that wearing PPE and BBG reduces reach envelope dimensions by 9% and 4%, respectively. Further, wearing a harness decreases reach envelopes by 29% and 17% for the PPE and BBG conditions, respectively.
