We are deeply grateful to William S. Murray, associate research professor at the Warfare Analysis and Research Division of the United States Naval War College’s Center for Naval Warfare Studies, for his guidance and sage counsel. Professor Murray’s insight into the People’s Liberation Army Navy and undersea warfare made him an excellent sounding board for us to bounce our ideas against. He also patiently helped us as we wrapped our heads around that tumultuous body of water that is the South China Sea. The generous allocation of his time and expertise is greatly appreciated.
