But even with such advances in materials, the weight of the armor required to manage threats of ever-increasing destructive capability presents a huge challenge. For example, body armor, which presently constitutes almost 30 percent of a soldier's fighting load,1 is the single largest weight carried by an Army rifle squad.

FIGURE 1-3 Areal density of armor versus time, demonstrating In this study, the committee was guided by military apthat new lightweight materials such as titanium, aluminum, and plications that necessitate lightweight armor, with particular ceramics have provided increased protection at a lower weight per emphasis on (1) personnel protection, which includes body unit area over time.
