Colonel Warner “Rocky” Farr has made an important contribution to the body of SOF knowledge with this well-researched monograph. He advances the understanding of the many challenges and accomplishments related to guerrilla warfare medicine—care provided by predominantly indigenous medical personnel under austere conditions with limited evacuation capability—by providing a survey of the historical record in UW literature. Colonel Farr relates many historical experiences in the field, assesses their effectiveness, and lays a foundation for further in-depth study of the subject. The Joint Special Operations University is pleased to offer this monograph as a means of providing those scholars and operators, as well as policymakers and military leaders, a greater understanding of the complex and complicated field of guerrilla warfare medicine.
