What is a type of joint team formed between two or more nations for a common action?

A coalition refers to a temporary alliance of nations formed for a specific purpose or common action, particularly in military contexts. This structure allows countries to combine their resources, capabilities, and strategic objectives to address shared threats or challenges effectively. The nature of coalitions is often characterized by flexibility, where nations come together for a defined mission or operation, especially in situations such as humanitarian assistance, peacekeeping, or military interventions.

While terms like "joint operations force" and "alliance group" denote collaborative efforts, they typically imply more permanent arrangements or structured alliances, such as NATO or other long-term partnerships. The term "unit coalition" is less commonly used and may not accurately capture the essence of coalition warfare as understood in military doctrine. Thus, the correct identification of a coalition highlights its role as a collective entity formed specifically for a common cause among multiple nations.
