The U.S. Army is hosting PC-C4, a Joint, Multinational, two-phase, “in-the-dirt” experiment from Feb. 23 – March 20, 2024. PC-C4 participants include the U.S. Army, U.S. Navy, U.S. Air Force, U.S. Marine Corps, and U.S. Space Force along with militaries from partner and allied countries from the United Kingdom, Australia, Canada, New Zealand, France, and Japan. PC-C4 is a culmination of numerous preceding exercises, experimentations, and events; it provides a critical venue to identify and refine recommendations necessary to transform the Army and ensure future war-winning readiness.
