The military response to Hurricane Sandy was historically significant. For the first time, dual status commanders-military commanders authorized by law to serve in both state and federal status simultaneously- were activated in an effort to unify state and federal efforts under a single command structure during an unplanned response. The events that occurred over the 2-week response period provide a basis for lessons learned as we look to improve upon this first attempt to use this unique command construct in response to an unplanned incident. In this monograph, Mr. Ryan Burke and Dr. Sue McNeil discuss the results of their year-long case study examining the military response to Hurricane Sandy under the dual status commander arrangement. In one of the most thorough and comprehensive analyses of the subject to date, Burke and McNeil first address the chronology of the storm and the ensuing military actions.
