Warfare in the Enemy's Rear - Otto Heilbrunn

This book, first published in 1963, is an analysis of modern warfare in the enemy's rear, written by the leading authority on irregular warfare, and stemming from a close examination of real-life examples. Rear warfare on scale poses many problems, such as the exact field of operations; supply line issues; combat or harassment; and coordination with frontline troops. There is also the issue of protecting one's own rear troops.
