This guide which, for years, has prepared military, emergency, and first responders to face psychological, social, and physical challenges of leading in dangerous contexts has been updated. The author team, which includes scholars and practitioners, has integrated current research findings, incorporated topics not covered in the prior edition and has created a reference work relevant to leaders at all levels (entry, mid, and senior) in organizations that operate in dangerous contexts. Leadership in Dangerous Situations, Second Edition includes nine new chapters that address character development, ethical decision-making and action, leading in uncertain times, empowering initiative, leading taskforces and cross-functional teams, operating in complex social and political environments, tactical and operational decision-making and planning, red teaming, and incident command. The authors wrote their chapters as acts of service to enhance the professions that serve their countries and societies.
