The U.S. Army’s Training and Doctrine Command’s Cultural Understanding and Language Proficiency (CULP) program for Cadets was created to achieve the objectives of the Army Culture and Foreign Language Strategy -- to produce officers who possess language and cultural skills. Program execution fulfils security cooperation objectives of Combatant Commands and Embassy Country Teams. Studies have shown the direct benefits CULP has had on developing cultural insights into foreign cultures but has overlooked and under-assessed the subsequent development of cultural insights into the inter-agency process of the 3Ds (Diplomacy, Development and Defense). This paper suggests that the Army needs to review its current Officer Professional Military Education and develop specific education, training, and policies targeted at developing joint, interagency, inter-governmental and multi-national (JIIM) competence earlier in an officer’s career. It discusses the potential of adding new objectives to the CULP program focused on JIIM competency development, potential opposition, and makes final recommendations.
