How do joint doctrine and wargaming support the development of multi-domain operations and integrated deterrence?

• A. They guarantee victory
• B. They replace field exercises
• C. They test assumptions, reveal inter-service dependencies, and guide iterative concept refinement
• D. They confirm plans without challenge

Answer: (C)

Joint doctrine and wargaming are about shaping how forces operate together across domains by challenging assumptions and building a shared understanding of interservice roles, timings, and dependencies. In multi-domain operations and integrated deterrence, this means testing how actions in air, land, sea, cyber, space, and the electromagnetic spectrum complement each other to achieve strategic effects, and doing so in a controlled environment before real-world execution.

Wargaming forces planners to surface hidden dependencies between services—where success in one domain hinges on timely support from another, or where information sharing, command and control, and logistics need tighter integration. Repeated play cycles reveal gaps, risks, and bottlenecks, guiding iterative refinement of concepts, architectures, and required capabilities so the overall approach becomes more coherent, feasible, and resilient under pressure. That iterative refinement is essential for credible deterrence, ensuring that the joint posture, signaling, and readiness are aligned across domains and capable of evolving as adversaries test and adapt. These tools don’t guarantee victory, nor do they replace field exercises or confirm plans without challenge; they provide a rigorous method to validate and improve the way the force plans to operate collectively.
