This interim report summarizes the findings of the Board for the first year of this biennial assessment; the current report addresses approximately half the portfolio for each campaign; the remainder will be assessed in 2016. During the first year the Board examined the following elements within the ARL's science and technology campaigns: biological and bioinspired materials, energy and power materials, and engineered photonics materials; battlefield injury mechanisms, directed energy, and armor and adaptive protection; sensing and effecting, and system intelligence and intelligent systems; advanced computing architectures, computing sciences, data-intensive sciences, and predictive simulation sciences; human-machine interaction, intelligence and control, and perception; humans in multiagent systems, real-world behavior, and toward human variability; and mission capability of systems. A second, final report will subsume the findings of this interim report and add the findings from the second year of the review.
