Multimedia representations of human activities in complex real-world settings, such as emergency response and military operations, can help participants, managers, and researchers to grasp the ramifications of decisions and actions in a dynamic environment. Gathering, organizing, and presenting relevant data from spatially and temporally distributed observation points are crucial steps in reconstructing the complex course of events of a tactical operation to enable exploration, analysis, and evaluation of the interaction between humans and systems in decision making and action. In a case study, we examine and classify multimedia representations of real-world operations in different domains and investigate how practitioners used them to explore the operations in retrospect. By identifying common representation patterns and presentation preferences we demonstrate the potential for reuse of models, methods, and tools across operations and domains. This step provides a crucial foundation for designing and implementing domain-independent, customizable frameworks that can support reconstruction and exploration in research, development, training, and operations.
