Critical infrastructure on many Department of Defense (DOD) installations are increasingly threatened by extreme weather, in part due to climate change and also in part due to the location vulnerability of these assets. At the same time, they are being relied upon more to ensure overall mission success. While each installation has its unique mission, we explore the mission at one installation – marine recruit training at the U.S. Marine Corps Recruit Depot in Parris Island, South Carolina – and predict how day-to-day and extreme weather events lead to infrastructure failures through statistical modeling. We then quantify what this means for installation operability by surveying individuals tasked with mission training. The results are informative for how to allocate resources for infrastructure enhancements in a way that protects base operability in addition to base infrastructure.
