Which term involves mission operations that utilize integrated forces across multiple domains?

The term that involves mission operations utilizing integrated forces across multiple domains is joint operations. Joint operations refer to the coordinated effort of different branches of the military, such as the Army, Navy, Air Force, and Marines, to achieve a common objective. This integration across various military domains—land, air, sea, space, and cyber—allows for more effective and efficient mission execution, as each branch brings unique capabilities and resources to the table.

In contrast, cyber warfare focuses specifically on operations in the cyber domain and may not involve the integrated efforts of multiple military branches. Amphibious tactics pertain to operations that involve moving forces from sea to land, predominantly used by naval and marine forces, but do not encompass the broader multi-domain integration. Land dominance refers to achieving control over land areas and does not necessarily imply the involvement of other domains or joint operations. Therefore, joint operations aptly describes the nature of integrating forces across different areas of military action.
