What is the different types of military action in the U.N?

The United Nations (U.N.) engages in various types of military action primarily through peacekeeping operations, enforcement actions, and collective security measures. Peacekeeping missions involve deploying troops to help maintain or restore peace in conflict zones, often with the consent of the host nation. Enforcement actions, authorized under Chapter VII of the U.N. Charter, involve military force to address threats to international peace and security, while collective security measures can include coalitions of member states acting together to respond to aggression. These actions aim to uphold international peace and security while adhering to the principles of the U.N. Charter.
