The General Assembly is a double delegation beginner committee.  

The General Assembly (GA)  is the main body of the United Nations. The General Assembly itself is split into six different committees, all with different focuses. This year's GA will represent the Third Committee, the Social, Humanitarian, and Cultural Committee (SOCHUM). This committee was created to address global social, humanitarian, and cultural challenges to maintain lasting peace. 

The specialized committee is a single delegation intermediate committee.

This year's specialized committee is the United Nations Educational, Scientific, and Cultural Organization (UNESCO). This body strives to maintain peaceful cooperation and interactions between global cultures. 

Security Council is a single delegation advanced committee.

The United Nations Security Council (UNSC) is the sole enforcing body of the United Nations (UN). It has 15 member states. The Permanent Five, Russia, China, the United States, France, and the United Kingdom, hold veto power, meaning that if any one of these member states votes no on a resolution, it immediately fails. The other 10 members are elected by the General Assembly for two-year terms.

The crisis is a single delegation intermediate committee.

This year's crisis takes place in a world much like ours, but supernatural entities from each country's folklore are now members of a special committee of the United Nations. Delegations from each supernatural group must participate in committee to build relationships, establish healthy boundaries, address issues with the integration of the new supernatural population, and respond to new threats.
