e. Authority of the Commander of a Unified Combatant Command in an
Emergency
(1) In the event of a major emergency in the GCC’s AOR requiring the use of all
available forces, the GCC (except for CDRUSNORTHCOM) may temporarily assume
OPCON of all forces in the assigned AOR, including those of another command, but
excluding those forces scheduled for or actually engaged in the execution of specific
operational missions under joint plans approved by SecDef that would be interfered with by
the contemplated use of such forces. CDRUSNORTHCOM’s authority to assume OPCON
during an emergency is limited to the portion of USNORTHCOM’s AOR outside the US.
CDRUSNORTHCOM must obtain SecDef approval before assuming OPCON of forces not
assigned to USNORTHCOM within the US. The commander determines when such an
emergency exists and, on assuming OPCON over forces of another command, immediately
advises the following individual(s) of the nature and estimated duration of employment of
such forces.
