The overall objectives of this section of the report were: 1) to conduct standardized assessment of five military systems on a computerized Load Carriage (LC) Simulator using a 50th percentile male manikin; 2) to conduct standardized assessments of three of these systems on a Stiffness Simulator; and 3) to examine the impact of different anthropometric manikins on two base systems. Specifically, the LC Simulator measured variables which assess the load control and load transfer to rotation about three orientation axes. Human responses during First Assessment and Standardized Tests (F.A.S.T.). Trials are reported in Section C and a comparison of these measured dimensions is validated in Section D of this report. The LC Simulator consisted of interchangeable anthropometrically weighted manikins (50th percentile male used) which were covered with a skin-like surface and driven by computer controlled pneumatic activators programmed to elicit a walking displacement pattern of +/=25.4 mm amplitude and 1.4 Hz frequency. A trial consisted of loading the pack to 25 kg(=/- 1 kg) payload, measuring system physical dimensions and properties, mounting the pack, and balancing the moments. Five intervals of 10 seconds of data were recorded over a 1200 second period. By this approach, the pack was assessed on the initial setup and after a sustained period of walking. TRUNCATED
