  MULTINATIONAL AND JOINT OPERATIONS
  2-29. The United States Army routinely conducts multinational operations. Multinational operations are
  conducted by two or more nations, usually in the form of a coalition or alliance. The JAG Corps, as part of
  the Army, operates with allies and partners. To the extent possible, the JAG Corps strives toward legal
  interoperability by fielding compatible systems, common procedures, and contingency plans that are
  compatible with allies and foreign partners even when the United States is operating alone, thereby preserving
  one process and one system. This reduces incompatibility or “relearning” once operations transfer from U.S.
  unilateral operations to multinational operations. The JAG Corps also strives to achieve understanding of the
  ways in which allies and partners interpret the law of armed conflict. (See FM 3-16 for more on multinational
  operations.)
