This article explores the development and application of an automated computer-aided wargame to establish high-level capability requirements and concepts of operations for future Navy unmanned aerial vehicles and unmanned underwater vehicles. The Joint Theater Level Simulation-Global Operations serves as the modeling environment, in which a computer-aided exercise models the impact of future intelligence, surveillance, and reconnaissance assets. Automating wargame simulations permits the replication of a large-scale exercise without the continued investment of support personnel and operating units. The environment enables experimentation that provides force planners with pertinent metrics to inform decision-making.
