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.

It takes place every day - business professionals evaluate the performance of an individual, a department or team, and perhaps even an entire company. However, for many managers, the process of evaluating performance is a dreaded corporate ritual that fails to cut to the chase and answer the question: “Did the performer achieve the objective, or not?” For nearly 35 years as a national and international management consultant, Mark Janacek has helped Fortune 500 organizations around the globe to improve individual, team and corporate performance. An avid and lifelong baseball fan, Janacek applies the simplicity of calling balls, strikes and outs against the strike zone as a model for evaluating performance in the business setting. The Strike Zone provides both a practical set of techniques, as well as a strong philosophical foundation for simplifying and strengthening the evaluation process across the entire business enterprise. For over three decades Janacek observed the hand-wringing frustration of both managers and staff struggling with evaluation systems failing to identify and truly reward excellence in performance, while correctly indicting poor performers that weigh down the organization. The Strike Zone is designed to reverse this agonizing trend, and vector corporate cultures to perform as never before. Janacek liberates well-meaning HR departments and company executives as he uncovers the ten most common evaluation traps found in many organizations. The Strike Zone provides specific, hard-hitting strategies to avoid them. Janacek’s cutting edge approach makes The Strike Zone a must-read for everyone competing in the business setting. Regardless of your position - owner, executive, manager, team leader, or individual contributor – The Strike Zone will surely engage you with keen insights, great depth of thought, and ignite those long lost passions for excellence.

The intense debate over US targeted drone strikes outside war zones has been limited by the failure to review and assess a considerable body of quantitative research and qualitative material on the impacts of such strikes on terrorist groups and civilians. This book fills an important gap in the literature by conducting a careful and rigorous review of such evidence. It argues that decisions about the use of targeted strikes as a counterterrorism instrument, as well as legal and ethical evaluations of such use, must be informed by our best understanding of the insights that empirical evidence can provide on the effectiveness of strikes and the costs they impose on populations where they occur.
