Which doctrine guides the organization and employment of air, space, and cyberspace forces?

The correct choice is operational doctrine, which serves as a framework outlining how air, space, and cyberspace forces are organized and employed to achieve military objectives. Operational doctrine focuses on the integration of various capabilities and approaches for using military resources effectively in a broader operational context. It provides guidance on how different forces can work together within joint and coalition settings, ensuring unified efforts towards mission success.

In contrast, basic doctrine is more foundational and addresses the fundamental principles of airpower. Tactical doctrine deals with the execution of specific missions at a lower level, focusing on the techniques and methods employed in specific engagements. Nuclear Surety doctrine is concerned with the safety, security, and reliability of nuclear weapons, which does not encompass the organization and employment of the broader range of air, space, and cyberspace forces. Thus, operational doctrine is the most comprehensive and relevant choice for guiding these forces.
