Also known as the First Committee of the UN General Assembly, it is the UN body that deals with disarmament, threats to peace, and global challenges that have an effect on the international community and seek out solutions to the issues in the international security regime.

It considers all disarmament and international security matters within the scope of the UN Charter or relating to the powers and functions of the other organs of the United Nations; the general principles of cooperation in the maintenance of peace and security, as well as principles regarding the way disarmament, should be reached; the promotion of cooperative agreements and measures aimed at ensuring stability in areas where there was a conflict or where there is still an ongoing conflict.

Also known as the Fourth Committee of the UN General Assembly, it considers a broad range of issues covering a cluster of five decolonization-related agenda items, the effects of atomic radiation, questions relating to information, a comprehensive review of the question of peacekeeping operations as well as a review of special political missions, the United Nations Relief and Works Agency for Palestinian Refugees in the Near East (UNRWA), Israeli Practices and activities affecting the rights of the Palestinian people and other Arabs of the occupied territories, and International cooperation in the peaceful uses of outer space.

Also known as the Sixth Committee, it is the major forum for the General Assembly's examination of legal issues. It has a specific responsibility to foster the gradual development of public international law, according to Article 13 of the UN Charter. Following precedent, this provision has been understood as a broad authorization to draft new treaties on a wide range of topics, adopt them, and recommend them to governments for signature, ratification, and accession. While international law-making conversations take place in a variety of United Nations specialised bodies depending on their actual subject area, those connected to general international law are normally held at the Sixth Committee.

The Security Council is a subsidiary organ of the United Nations that has primary responsibility for the maintenance of international peace and security. It has 15 Members and it is the only committee whose decisions are binding to all Member States under the Charter of the United Nations.

It has five permanent members (the P5) holding the Veto Power (the French Republic, the People’s Republic of China, the Russian Federation, the United Kingdom of Great Britain and Northern Ireland and the United States of America) and 10 non-permanent members.

The Security Council has the priority of seeking peaceful solutions for any problem discussed by it, yet in severe situations that threaten international security, they may authorise peacekeeping forces to intervene and they may also call upon the Member States of the United Nations to apply diplomatic and economic sanctions to a target state, individual or group of individuals.

A crisis committee is a decision-making body that has more power than a traditional committee. Whilst General Assemblies recommend and build consensus, focusing on creating and refining frameworks for nations to align their actions, Crisis Committees produce action. The Crisis is more dynamic and fast-paced than traditional committees, so each delegate is incredibly influential. The Crisis itself provides a common evil for all the delegates, but each party has a different approach to solving it, which brings alliances, betrayals and winners. The Crisis Committee functions based on Directives which help influence the course of the dispute. Directives are individual, group or cabinet actions that interfere directly with the crisis, they can either be secret, to provide a sneakier approach or public.

The United Nations Economic and Social Council (ECOSOC) is one of the six principal organs of the United Nations, overseeing the economic and social sectors of the organization. Under its jurisdiction, there are 15 specialized agencies, 8 functional commissions and 5 regional commissions.

The ECOSOC Committee serves as the central forum for discussing international economic and social issues, while also elaborating policy recommendations. Since 1998, the ECOSOC has held a four-week session once a year, in July. Moreover, there is an annual meeting held in April where finance ministers of crucial committees of the World Bank and the International Monetary Fund (IMF) are called.

The World Health Organization (WHO) is a United Nations specialised organisation in charge of worldwide public health. The WHO Constitution declares its primary purpose is "the achievement of the greatest attainable degree of health by all peoples." Its headquarters are in Geneva, Switzerland, with six regional offices and 150 field offices across the globe.

The WHO's mission includes promoting global health, maintaining international security, and assisting the disadvantaged. It pushes for a billion additional people to have universal health care coverage, participation in the monitoring of public health hazards, coordination of responses to health crises, and promotion of health and well-being. It helps nations with technical aid, establishes worldwide health standards, and gathers data on global health challenges. The WHO also functions as a venue for health-related debates.
