“The National Defense Authorization Act of 2008 established the Yellow Ribbon Reintegration Program (YRRP) to assist National Guard and Reserve members as they transition between their military and civilian roles. By providing deployment cycle information, resources, and programs, YRRP addresses the unique challenges facing the Guard and Reserve community, including geographic dispersion away from military support networks and fewer deployment resources than the Active Component.
