Includes 10 detailed tables ‘War is often depicted in the textbooks as a well-orchestrated, albeit violent, exercise in which opposing units strive to achieve tactical and strategic objectives. That each side will suffer casualties in the process is taken for granted; they are the inevitable, if regretable, consequence of such a deadly undertaking. That each side is almost certain to suffer casualties inflicted by its own forces is not generally taken for granted. Yet, in each of America’s wars, especially those of the twentieth century, a significant number of soldiers have been killed or wounded as the result of friendly fire. The fact that the percentage of casualties resulting from friendly fire from World War I through Vietnam has been extremely low does not make the accidental killing or wounding of one’s own troops any less tragic or unpalatable. Nor does it offer much consolation to the commander responsible for the lives of his troops or to the soldier who runs the risk of falling victim to the fire of his own forces. To be sure, each branch of the Army and each of the Armed Services employ measures calculated to prevent incidents of friendly fire...Before one can undertake a serious and comprehensive analysis of friendly fire, these data must be found and brought together in one place. In Amicicide: The Problem of Friendly Fire in Modern War, LTC Charles R. Shrader has taken a major step toward the compilation of these data. In his well-informed narrative, he draws tentative conclusions about the causes and effects of friendly fire and offers recommendations for those who expect to study the subject further. He has, in short, produced a superb reference book and a springboard for a deeper and more comprehensive analysis of this grim and complex problem.’-Foreword

From surveys of much of the existing literature on World War I, World War II, the Korean War, and the Vietnam War, the author has extracted examples of friendly fire involving U.S. ground forces and has categorized them according to types of incidents. In this narrative, he draws tentative conclusions about the causes and effects of friendly fire and offers recommendations for those who expect to study the subject further.

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.

In the seventy years that have passed since the tank first appeared, antitank combat has presented one of the greatest challenges in land warfare. Dramatic improvements in tank technology and doctrine over the years have precipitated equally innovative developments in the antitank field. One cycle in this ongoing arms race occurred during the early years of World War II when the U.S. Army sought desperately to find an antidote to the vaunted German blitzkrieg. This Leavenworth Paper analyzes the origins of the tank destroyer concept, evaluates the doctrine and equipment with which tank destroyer units fought, and assesses the effectiveness of the tank destroyer in battle.
