A longitudinal study of infections and injuries of Ranger students

Causes of medical attrition and their implications for medical support for the U.S. Army Ranger course are considered, based on data collected from 190 students in a summer class. In the second half of the course, an increase in documented infection rates, notably cellulitis of the lower extremities and Streptococcus carriage prevalence, coincided with indications of compromised immune function. The authors suggest that aggressive treatment in the field, including liberal use of antibiotics, and periodic examination of each student by medical personnel are critical factors which will minimize medical attrition and ensure safe participation of soldiers in this and other stressful and sustained field exercises.
