From the Document: "As a result of the nation's extended involvement in contingency operations around the globe, some servicemembers have experienced prolonged, frequent, and/or stressful deployments. In addition, preparation for deployments (e.g., training, exercises, temporary duty assignments) can lead to extended working hours or frequent travel away from home station. The pace of operations for individuals is commonly referred to as 'personnel tempo' (PERSTEMPO) and can affect quality of life, work satisfaction, and overall morale for members and their families."
