As military tactics evolve toward execution centric operations the ability to analyze vast amounts of mission relevant
data is essential to command and control decision making. To maintain operational tempo and achieve information
superiority we have developed Vigilant Advisor, a mobile agent-based distributed Plan Execution Monitoring system.
It provides military commanders with continuous contingency monitoring tailored to their preferences while
overcoming the network bandwidth problem often associated with traditional remote data querying. This paper presents
an overview of Plan Execution Monitoring as well as a detailed view of the Vigilant Advisor system including key
features and statistical analysis of resource savings provided by its mobile agent-based approach.
