Coalition forces refer to military groups formed by multiple countries working together to achieve a common goal, often in response to international conflicts or crises. These forces can include troops, equipment, and resources from various nations, united under a shared mission, such as peacekeeping or combating terrorism. Historically, coalition forces have been involved in significant operations, such as the Gulf War in the early 1990s, where a coalition of countries, including the United States and United Kingdom, worked together to liberate Kuwait from Iraqi occupation. Such collaborations aim to enhance military effectiveness and share the burden of international security efforts.
