... This means that objects that radiate in the infrared range can be discerned by the appropriately equipped soldier in low ambient light conditions. Furthermore, high-intensity infrared sources now can be used for communication purposes or to illuminate targets without revealing intent or position to hostile forces that are not so equipped.

... The compounded problem in this area comes from the fact that the body has reflexes and highly overlearned muscular compensation responses when moving at different speeds. Thus, whereas the ideal location of any weight on the head might be centered on the vertical line connecting the body's center of gravity and the head's center of gravity, the situation is complicated by the postural changes as one shifts from an erect, standing position to a slow walk, to a fast walk, to a jog, and to a run.

... , care must be exercised with respect to any attachments to the helmet. Of particular concern should be the use of wires or cables that provide electronic connections from the helmet-mounted display with other equipment such as remote gun sights and navigation gear such as the global position system and computer equipment.

... The lack of direct comparability between the research on helmets and helmet-mounted displays for vehicular crew members and the conditions that are experienced by the dismounted soldier provides a strong argument for a comprehensive program of laboratory research augmented by small-scale simulated engagement tests. The laboratory tests should be mainly directed to the helmet per se and the liner and support cushioning materials.

... However, human factors design principles can be interpreted to fit the specific ergonomic issues posed by the proposed system: The helmet and its attachments should be as light weight as possible while fulfilling the objective of providing ballistic protection. The attachments, including cables and wires, should extend as short a distance as possible from the head and body of the soldier.
