Nine psychomotor tasks designed for laboratory use measured the performance of 18 soldier test subjects while wearing M1956 Lightweight Load Carrying Equipment LCE alone and over standard 135 plate and experimental 48 plate titanium-nylon body armor. Scores based on LCE only, on experimental armor and LCE, and on standard armor plus LCE are compared. In laboratory interviews, subjects appeared to prefer load carrying equipment worn without armor to LCE worn over either type of armor, and they commented on specific armor problems. Next, a lightweight cloth sensor garment incorporating pressure sensors was used to measure pressure at various locations on a test subjects torso as he performed task. Performance and display were recorded in color on the same motion picture film, for each of six armor-load combinations.
