4-219. All state and federal military forces involved in DSCA must understand and apply important distinctions regarding state RUF and federal SRUF. First, states that provide National Guard forces in state active duty or Title 32, USC duty status to another state normally adopt the RUF of the supported state for those operations. The states involved normally specify in their memorandum of agreement the RUF the forces will follow. Second, a state's RUF do not apply to federal forces operating in that state. Third, when state and federal forces are operating in overlapping operational areas, the SRUF for federal forces do not apply to the state forces, even when the state forces are operating in Title 32, USC status on missions assigned by DOD.
