In today’s complex global security environment, military effectiveness depends not only on advanced technology and tactics but also on the ability to understand, communicate, and collaborate across cultures. This interdisciplinary volume examines the evolving role of language, regional expertise, and cultural competency (LREC) in U.S. military training, strategy, and leadership.

Drawing on insights from both military and academic contributors, this collection offers a timely and authoritative overview of how LREC competencies support deterrence, interoperability, influence operations, and alliance-building for the warfighter.
