Soldier Performance and Functionality: Impact of Chemical Protective Clothing

Abstract

This article describes the components of the chemical protective uniform used by U.S. Army infantry and other ground troops and presents research on the effects of the clothing on soldier performance. The clothing has been found to impose not only a thermal burden but also a mechanical burden. Respirators restrict the visual field and affect speech intelligibility. Body movements are limited by the clothing; manual dexterity capabilities and psychomotor performance can also be negatively impacted. In addition, wearing the clothing may induce psychological stress. Symptoms include breathing distress, tremors, and claustrophobia. Efforts described here are underway to address performance issues during development of new protective uniforms. Research needed to address psychological issues is also suggested.
