The document outlines changes to the Overseas Contingency Operation Support Assignment (OSA) program that aim to preserve desirable elements and mitigate unintended consequences of the Global Sailor program. Key changes include enlisted sailors selecting OSA interest 2-3 months before detailing to be sourced in real-time by OSA detailers, eliminating PCS orders for OSA with sailors administratively attached to their parent command, and providing post-OSA choice of coast detailing while exempting sailors from involuntary assignment for 3 years. The changes reduce administrative burdens, increase flexibility, and provide stronger family and command support for sailors participating in OSA.
