Book excerpt: The material in this memorandum supplements readings presented in the volume, Modern Guerrilla Warfare, edited by Franklin Mark Osanka and published in 1962, and together they will give the reader a comprehensive cross-section of the many facets of guerrilla warfare. The first two readings are a concise review of guerrilla warfare from ancient times to the present. The next three readings are devoted to Soviet guerrilla activities against the Nazis during World War II and to current Soviet emphasis on this form of warfare. The last five readings are concerned with counterinsurgency procedures and policies for the future. Atkinson argues that unconventional warfare will play an ever-increasing role in future wars.
