This Leavenworth Paper is a critical reconstruction of World War II Ranger operations conducted at or near Djebel el Ank, Tunisia; Porto Empedocle, Sicily; Cisterna, Italy; Zerf, Germany; and Cabanatuan in the Philippines. It is not intended to be a comprehensive account of World War II Ranger operations, for such a study would have to include numerous minor actions that are too poorly documented to be studied to advantage. It is, however, representative for it examines several types of operations conducted against the troops of three enemy nations in a variety of physical and tactical environments. As such, it draws a wide range of lessons useful to combat leaders who may have to conduct such operations or be on guard against them in the future. Many factors determined the outcomes of the operations featured in this Leavenworth Paper, and of these there are four that are important enough to merit special emphasis. These are surprise, the quality of opposing forces, the success of friendly forces with which the Rangers were cooperating, and popular support.

Friendly fire incidents often disrupt the close and continuous combined arms cooperation so essential to success in modern combat, especially when that combat is conducted against a well armed, well trained, and numerically superior opponent. This study, by presenting selected examples in their historical settings, is intended only to explain a few of the most obvious types of friendly fire incidents and some of the causative factors associated with them. By directing the attention of commanders and staff officers responsible for the development, training, and employment of combat forces to the hitherto little explored problem of friendly fire incidents, this study is intended to generate interest in and solutions for the problems outlined. The scope of this study is limited to incidents involving US forces in World War II and Vietnam, although some evidence is available from other conflicts in the twentieth century has also been considered. In sum, this study can claim to be no more than a narrative exposition of selected examples. Although its conclusions must be considered highly speculative and tentative in nature, this study can be of substantial value to an understanding of the problem of friendly fire in modern war. Chapters one through 5 of this report discuss: Artillery Amicicide; Air Amicicide; Antiaircraft Amicicide; Ground Amicicide.

[Includes 53 photos/illustrations and 11 maps] The defense of Bastogne during the Battle of the Bulge in World War II is one of the supreme achievements of American arms. Bastogne is deservedly identified with the finest characteristics of the American soldier, and the name Bastogne symbolizes a heroic battle. Bastogne has long held the attention of students of war, yet the battle offers new insights for soldiers with modern concerns. Colonel Ralph M. Mitchell’s study, The 101st Airborne Division’s Defense of Bastogne, reveals how a light infantry division, complemented by key attachments, stopped an armor-heavy German corps. Using original documents and reports, Colonel Mitchell traces the fight at Bastogne with emphasis on the organization, movement and, employment of the 101st Airborne Division. Although a variety of factors influenced the outcome at Bastogne, the flexibility of the 101st to reconfigure for sustained operations and to defeat strong opposition forces even when surrounded shows how properly augmented light infantry can fight and win.
