With the rise of China and the return of Russia to near-peer military status with the United States, the topic of renewed Great Power Competition (GPC) has moved to the forefront of U.S. defense concerns.  In 2019, in response to a request from N3/N5, the Department of National Security Affairs at NPS created a first-of-its-kind GPC overview course to educate NPS students and interested faculty and staff about critical challenges posed by China and Russia.
