The effects of functional limitations on soldier common tasks

Area of Science:

• Military Science
• Human Factors Engineering
• Occupational Health

Background:

• Soldiers must master essential tasks for mission success and safety.
• Standardized training ensures proficiency in critical skills.
• Understanding performance barriers is key to optimizing soldier capabilities.

Purpose of the Study:

• To evaluate soldier performance on key tasks, including rifle maintenance and CBRN protection.
• To identify specific elements that introduce abnormal or extraneous effort during task execution.
• To inform improvements in training and equipment based on observed performance.

Main Methods:

• Analysis of video data from soldiers performing common tasks.
• Focus on tasks such as M16-Series Rifle maintenance and use of Mission-Oriented Protective Posture (MOPP) gear.
• Utilized data from Walter Reed Army Medical Center for task performance evaluation.

Main Results:

• Identified specific actions and environmental factors contributing to increased physical or cognitive load.
• Findings highlight potential inefficiencies in current task execution methods.
• Performance variations were noted across different common soldier tasks.

Conclusions:

• Task performance analysis can reveal areas for procedural or equipment refinement.
• Optimizing soldier performance requires understanding and mitigating extraneous effort.
• Recommendations for enhancing Soldier's Manual of Common Tasks (STP-21-1-SMCT) training and execution are suggested.
