“The Army needs to take its concept and undertake a series of wargames focused on real-world contingencies, particularly those relating to the defense of the First Island Chain in the Pacific and NATO’s frontline states in Eastern Europe,” said Andrew Krepinevich of the Center for Strategic & Budgetary Assessments, whose work on so-called Anti-Access/Area Denial threats and how to counter them informs much of Multi-Domain Battle. “These games should inform a series of field exercises that provide insight on force design and operational concepts that can inform the service’s resource priorities.”
