• A study analyzing performance under acute stress during hand-to-hand combat experiences of soldiers, done by Peter R. Jensen (New Mexico State University) and Craig A. Wrisberg (University of Tennesse) indicate the following:
  • The hand-to-hand combat experiences of these soldiers comprise stressors stemming from a variety of sources
  • Their combat experience demanded a speedy and accurate interpretation of surrounding conditions, and the swift strategizing coupled with focused action
  • The experience also produced powerful psychological and physiological reactions
• It was also concluded that the following could enable better performance
  • Expecting the unexpected in potentially dangerous yet seemingly routine operations
  • Building highly automated and problem focused fighting skills and coping methods
  • Training in unpredictable and variable environments requiring swift skill adaptations based on stressors unique to each context.
