  authority and reporting requirements vary depending on the duration and type of support requested. The
  President may direct any agency of the Federal government to undertake missions and tasks on either a
  reimbursable or nonreimbursable basis.
  AGREEMENTS
  2-174. Different agreements are designed to establish a common understanding between nations,
  governments and organizations. Financial managers must be aware of these agreements and follow them
  with extreme caution since the impact has a higher relevancy during operations involving other allies,
  Services or international organizations.
  United Nations Letter of Assist
  2-175. A UN letter of assist (LOA) is a document issued by the UN to a contributing government
  authorizing that government to provide goods or services to UN peacekeeping forces. An LOA typically
  details specifically what is to be provided by the contributing government and establishes a funding limit
  that cannot be exceeded. General support LOAs can be negotiated with the UN (if such LOAs are
  advantageous to both parties) to cover more generic categories, such as subsistence, fuel, sustainment, and
  spare parts. More than one item or service can be included on an LOA. LOAs are considered by the UN to
  be contracting documents and must be signed and issued by the UN Director, Field Operations Division.
  The LOA is not considered a funded order, and the UN does not normally provide an advance of funds for
  the value of the LOA.
  2-176. The UN reimburses contributing countries for the costs of their activities IAW UN standard
  procedures covered in the “United Nations Guidelines to Contributing Governments” and specific and
  general LOAs. The UN should approve all elements of national contributions and the extent of
  reimbursement prior to an actual deployment, if possible. Therefore, activities undertaken, troops deployed,
  or costs incurred for items and services rendered that are not agreed to in advance by the UN are not
  normally reimbursed by the UN. Only expenditures in support of an operation approved by the Security
  Council and authorized by the General Assembly as a legitimate charge to the UN are eligible for
  reimbursement.
  Acquisition and Cross-Servicing Agreement, 10 USC 2342
  2-177. Purpose. The purpose of the ACSA authority provided under 10 USC 2342 is to acquire or
  transfer logistic support outside the Arms Export Control Act channels. Under this authority, the DOD,
  after consultation with DOS, may enter into agreements with NATO countries, NATO subsidiary bodies,
  other designated eligible countries, the UN, and other international regional organizations of which the
  United States is a member that provide for the reciprocal provision of logistic support, supplies, and
  services. This authority is limited to the purchase and sale of logistic support and does not extend to major
  end items of equipment such as trucks or weapons systems. As a result of the FY 1995 National Defense
  Authorization Act changes, the DOD is authorized general-purpose vehicles and other nonlethal items of
  military equipment that are not designated as significantly military equipment on the U.S. munitions list.
  Examples include vehicles, communications equipment, and training aids.
  2-178. Procedures. After consulting with DOS, the DOD may enter into agreements with NATO
  countries, NATO subsidiary bodies, and other designated eligible countries for reciprocal logistic support,
  supplies, and services. However, major end items are excluded. Acquisitions and transfers are on a payment
  in cash, replacement in kind (RIK), or equal value exchange (EVE) basis. RIK or EVE must be
  accomplished within 12 months after the date of delivery of the logistic support, supplies, or services. After
  12 months, reimbursement must be on a cash basis.
  2-179. Examples. This authority was used extensively in the early phase of Somalia operations. This
  authority also provided logistic support, supplies, and services to the French-led coalition peace
  enforcement effort Operation TURQUOISE in Rwanda. This authority has also been used in peace
  operations conducted by member state coalitions under UN auspices (for example, the Unified Task Force
  phase of the Somalia operations with Canadian and Australian forces). ACSAs have been used in Bosnia
  and Kosovo.
