Warfighter Support: DOD Needs a Complete Picture of the Military Services' Prepositioning Programs, Report to the Committee on Armed Services, U.S. Senate [open pdf - 2MB]
From the Highlights: "The U.S. military services preposition critical assets at strategic locations around the world for access during the initial phases of an operation. DOD uses these prepositioned assets for combat, support to allies, and disaster and humanitarian assistance. For many years, GAO [Government Accountability Office] has identified weaknesses in DOD's efforts to establish a joint oversight framework to guide its ability to assess the services' prepositioning programs. This has led to fragmentation and the potential for duplication. Senate Report 116-48 included a provision for GAO to evaluate the services' prepositioning programs and associated challenges. This report (1) describes the types of assets the services preposition worldwide, as well as asset shortfalls and challenges the services have identified, and (2) assesses the extent to which DOD has made progress in implementing a joint oversight framework for the services' programs. To conduct this work, GAO reviewed DOD prepositioning documents and interviewed DOD and State Department officials from over 20 offices. This is a public version of a sensitive report that GAO issued in December 2020. Information that DOD deemed sensitive has been omitted."
