Black Sea Rotational Force began in 2010 with the purpose to form a Security Cooperation Marine Air-Ground Task Force. The forward postured troops' ability to conduct military-to-military engagements with partner nations in Eastern Europe while providing the capacity for rapid crisis response made it an essential year-round mission to U.S. European Command (EUCOM) and their partners in the Eastern European Theater. The biannual rotation of Marines and sailors with BSRF are postured at the Mihail Kogălniceanu Airbase, Romania, which enables the continuation of promoting regional stability, increasing interoperability, and building and maintaining enduring partnerships with allied and partner nations.
