News of the Marines' shift to a more traditional mission with echoes of the World War II Pacific Campaign was first undertaken by Commandant General David Berger, appointed in 2019 by then-President Donald Trump, under whom a severe downturn in relations with China first occurred. The new techniques have since been demonstrated in a series of exercises, including this April's Noble Fury off the coast of Japan and July's Summer Fury off the coast of California.
One of these techniques is a new training program called the Infantry Marine Course (IMC), which a U.S. Marine Corps Training and Education Command official told Newsweek was "a direct reflection of the Commandant's Planning Guidance that dictates the requirement for smarter, better-trained multi-disciplinary infantry Marines."
