Noncombatant Evacuation Operations (NEO)
How U.S. embassies plan and execute Noncombatant Evacuation Operations — the F-77 list, the Emergency Action Plan, and State–DoD coordination.
The statutory and policy architecture
A Noncombatant Evacuation Operation (NEO) is the assisted departure of U.S. citizens, designated third-country nationals, and locally employed staff from a host country whose security environment has collapsed. The authority structure is bifurcated: the Secretary of State retains policy responsibility for the protection of U.S. citizens abroad under 22 U.S.C. § 2671 (the Emergencies in the Diplomatic and Consular Service appropriation) and 22 U.S.C. § 4802 (the Secretary's protection-of-personnel mandate enacted in the Omnibus Diplomatic Security and Antiterrorism Act of 1986). The Secretary of Defense executes the physical evacuation when conditions exceed commercial means, pursuant to 10 U.S.C. § 822 and the long-standing Memorandum of Agreement between State and DoD on the Repatriation of U.S. Citizens, most recently updated in 2017.
The Chief of Mission (COM) is the on-scene decision authority. National Security Decision Directive 38 (NSDD-38, 1982) gives the ambassador control of the size, composition, and mission of all U.S. government personnel at post — including, critically, the authority to request or refuse military forces during a NEO. The geographic Combatant Commander (e.g., AFRICOM, CENTCOM, EUCOM) is the supported commander for execution, but operates in support of the COM. This inversion of the normal military command relationship is codified in Joint Publication 3-68, Noncombatant Evacuation Operations.
The three drawdown postures
State Department practice recognizes a graduated sequence before a full NEO is ordered. Authorized Departure (AD) permits voluntary evacuation of eligible family members and non-emergency personnel at U.S. government expense; it is approved by the Under Secretary for Management for up to 30 days and renewable to 180 days under 3 FAM 3774. Ordered Departure (OD) is mandatory for designated categories and is the immediate predecessor to suspension of operations. Evacuation — the NEO itself — is invoked when the host government can no longer guarantee the safety of the mission or when commercial transportation has ceased.
The planning instrument is the post's Emergency Action Plan (EAP), maintained by the Emergency Action Committee (EAC) and reviewed annually under 12 FAH-1. Embedded within the EAP is the F-77 Report, the classified estimate of U.S. citizens potentially requiring evacuation assistance, broken down by location, mobility status, and dual-national status. The F-77 is updated quarterly and drives DoD lift planning — if Embassy Khartoum's F-77 lists 16,000 private U.S. citizens, CENTCOM sizes the evacuation force accordingly.
Historical execution provides the reference cases. Operation Eastern Exit (Mogadishu, January 1991) extracted 281 evacuees by CH-53E helicopters from USS Guam and USS Trenton after Ambassador James Bishop's request. Operation Assured Response (Monrovia, April 1996) evacuated 2,126 personnel during the Liberian civil war. Operation Shining Express (Monrovia, June 2003), Operation Safe Departure (Lebanon, July 2006) which moved roughly 15,000 Americans, and the Kabul NEO of 14–30 August 2021 under Operation Allies Refuge — which evacuated approximately 124,000 people — each followed the same legal sequence: COM request, Secretary of State concurrence, Secretary of Defense execute order, Combatant Command operational control. The Kabul case also illustrated the consequence of delayed OD: the Embassy was not placed on Ordered Departure until 12 August 2021, two days before Taliban forces entered the capital, compressing destruction of classified holdings and personnel withdrawal into hours rather than days.
