Purpose: This pamphlet provides general guidance and framework for the planning and implementation of international capacity development (CD) for programs and projects conducted or supported by the U.S. Army Corps of Engineers (USACE). Engineer Regulation (ER) 5-1-16 (Capacity Development – International) has been developed as a companion document to this EP. ER 5-1-16 sets the USACE policy and serves as the requirements basis document for planning and implementation of CD on USACE international programs and projects.
