This study compared the mounting time and strain on the head-neck while using an old model (forehead and cheek supported) and a new model (head harness supported) of head-mounted night vision goggle systems in the postures of standing, sitting, and lying prone. The results showed that effectively reducing the mounting time was attributed to the ease and less time required for length adjustments of the head harness in the new model. The novel device received higher positive subjective ratings for convenience and comfort while wearing than did the old model. Although the weight of the new model was decreased to 0.794 kg and the length was reduced to 0.155 m, the loads on the head-neck complex remained high. These findings suggest that a rifle should be fitted with the night vision goggle or handheld model to decrease neck-shoulder workload if the prone position is the most frequent and important posture for soldiers.
