This document provides an overview of the National Guard State Partnership Program (SPP), which partners National Guard organizations with foreign countries' defense forces. It began in 1992 with partnerships in Central and Eastern Europe to support security cooperation goals. The program has since expanded globally and now includes 68 partnerships with 74 countries. Through exchanges, exercises, training, and other collaboration, the SPP aims to build long-term, enduring relationships between National Guard and partner country personnel. These relationships support U.S. geographic combatant commands and have enabled cooperation on missions like Iraq, Afghanistan, and peacekeeping operations. The SPP is now recognized as an effective security cooperation model that strengthens alliances and partnerships in a cost-effective manner.
