Defense Transportation: DOD Can Better Leverage Existing Contested Mobility Studies and Improve Training, Report to Congressional Committees [open pdf - 2MB]
From the Highlights: "China and Russia are strengthening their militaries to neutralize U.S. strengths, including mobility--the ability of U.S. military airlift and air refueling aircraft and sealift ships to rapidly move equipment and personnel from the United States to locations abroad to support DOD missions. Senate Report 116-48 included a provision for GAO [Government Accountability Office] to review DOD's ability to operate in a contested mobility environment. This report assesses the extent to which DOD has studied contested mobility and tracked the implementation of study recommendations, assesses the extent to which DOD has revised its training to incorporate contested mobility challenges, and describes the technologies that DOD uses to mitigate contested mobility challenges."
