This program was directed toward investigating the feasibility of Variable Armor Concepts which would provide selective and variable levels of protection to the infantryman. Concepts of variable armor comprising differential protection were originated. Guidelines are suggested for improved future families of infantry protective garments. They are not intended to suggest an optimum design but to portray the results of preliminary investigation. These results enable the investigator to conduct a trade-off study which will form the basis for an optimum approach in a finalized system. Variability of ballistic protection is accomplished through several approaches. Rigid elements of varying areal densities are inserted into pockets of a basic ballistic garment. The basic garment provides protection against low-level fragmentation for the posterior and anterior thoracic-abdominal torso and peripheral areas. Rigid or flexible elements of varying areal densities are inserted into a basic carrier resulting in differential protection. Flexible elements for low-level fragmentation protection are provided in the peripheral areas rigid elements for the anterior and posterior torso are employed to protect the vital organs from small arms fire. A basic flexible garment for maximum coverage and low-level fragmentation protection is combined with overlay rigid elements of varying area densities and area coverage, in a separate carrier.
