Logistic support during multinational operations differs from unilateral joint operations in that the participating nations represent different national and military objectives, cultures, and approaches to logistic support. This impacts how the US organizes, prepares, and executes logistic support during multinational operations. A significant challenge in multinational logistics (MNL) involves establishing effective command and control (C2) processes that are acceptable to all troop contributing nations. The joint logistics environment exists at the strategic, operational, and tactical levels of war. Operations are distributed and conducted rapidly and simultaneously across multiple operational areas within a single theater or across boundaries of more than one geographic combatant commander and can involve a variety of military, interagency, nongovernmental organizations, commercial, and multinational partners.
