Country Team Mechanics and ICASS
How U.S. embassies coordinate interagency operations through the Country Team and allocate shared platform costs through the ICASS cost-distribution system.
The Chief of Mission's Statutory Authority
The Country Team is the senior interagency coordinating body at every U.S. diplomatic mission abroad, chaired by the Chief of Mission (COM) — the Ambassador, or in the Ambassador's absence the Deputy Chief of Mission (DCM) as Chargé d'Affaires ad interim. Its authority derives not from custom but from statute. Section 207 of the Foreign Service Act of 1980 (22 U.S.C. § 3927) vests the COM with full responsibility for the direction, coordination, and supervision of all U.S. executive branch employees in country, except those under command of a U.S. area military commander or on the staff of an international organization. President Kennedy first codified this principle in his letter of May 29, 1961 to all chiefs of mission; every president since — most recently President Biden's letter of July 16, 2021 — has reissued substantially identical guidance directing that the Ambassador has "full responsibility" for all executive branch personnel and activities.
Composition and Cadence
A standard Country Team includes the DCM, the heads of the political, economic, consular, management, and public affairs sections, the Regional Security Officer (RSO), the Defense Attaché (DATT) and Senior Defense Official, the USAID Mission Director, and the chiefs of any other agencies present — typically DEA, FBI Legal Attaché, Department of Homeland Security (CBP, ICE/HSI), Commercial Service, Foreign Agricultural Service, Treasury, and, where applicable, the Chief of Station representing the intelligence community. At larger posts the Country Team may exceed 25 agencies; Embassy Baghdad at its 2011 peak hosted personnel from more than 30 U.S. government entities.
The Country Team typically convenes weekly, often Monday mornings, for a 60–90 minute meeting at which each principal reports developments, flags equities, and surfaces requests for the Ambassador's intervention. Decisions taken bind all agencies at post regardless of their Washington reporting chains. An agency representative who disagrees with a COM decision may appeal through their own Washington headquarters, but must comply at post pending resolution — the so-called "obey now, grieve later" rule.
NSDD-38 and Personnel Footprint Control
The COM's gatekeeping power over mission size is exercised through National Security Decision Directive 38, signed by President Reagan on June 2, 1982. NSDD-38 requires any U.S. government agency seeking to add, subtract, or change the personnel composition of its staff at a post — including locally employed staff and contractors — to obtain the Chief of Mission's written approval. Requests are submitted via cable to the Bureau of Administration and routed to post; the COM may approve, disapprove, or condition the request on space, security, or ICASS cost considerations. NSDD-38 reviews became a flashpoint after the September 11, 2012 Benghazi attack, when the Accountability Review Board chaired by Ambassador Thomas Pickering criticized inadequate scrutiny of personnel ceilings against security capacity.
The COM's authority is not unlimited. Section 207(a)(1)(B) carves out personnel under a U.S. area military commander — meaning combatant command forces operating under a Status of Forces Agreement remain in the military chain. The boundary is negotiated bilaterally between the COM and the geographic combatant commander through a Memorandum of Agreement; the 2012 MOA between Ambassador Anne Patterson and CENTCOM for Egypt is a frequently cited template.
