MOOTW not involving the use or threat of force include humanitarian assistance and disaster relief. Special agreements exist which facilitate fire support operations within NATO and the ABCA quadripartite working group, which includes American, British, Canadian and Australian military contingents. Cooperation is organized in advance with NATO standardisation agreements (STANAGs) and quadripartite standardisation agreements (QSTAGs). Many countries which need disaster support relief have no bilateral agreements already in place; and action may be required, based on the situation, to establish such agreements.
