Strategic Decisions from Wargaming?

In my early days worked with the DOD,  Used wargaming, but mostly about testing new technology as part of operational warfighting decisions.  Not broader strategy decisions.    So this interests me.

What Strategic Decisions on the Horizon for the Department of Defense Can Best Be Shaped Through Wargaming?
by Sebastian Joon Bae  RAND

Two strategic decisions hang heavy over the Department of Defense (DoD): 1) How does the DoD redesign the Joint Force to meet the challenges of future contingencies and wars? 2) How will the department pay for it? These questions are not new, but their importance cannot be understated. For years, all the services have been diligently pursuing potential answers, spurring a litany of emerging warfighting concepts and organizational restructuring. Examples abound from the Army's Multi-Domain Operations (PDF) and the Marine Corps' Expeditionary Advanced Base Operations to the establishment of Air Force Warfighting Integration Capability and Army's Future Command.

So, how could wargaming shape these decisions? The answer is simple: wargaming is already an integral part and should continue to be. As an incredibly adaptable analytical tool, wargaming can examine competing courses of action, explore the effects of emerging technologies, and assess operational concepts. This is reflected in the plethora of wargames examining the future force, both within the military and its federally funded research and development centers.

The role of wargaming in the ongoing transformation of the Marine Corps serves as a poignant example. In his 2019 Commandant's Planning Guidance, General David H. Berger, 38th Commandant of the Marine Corps (CMC), repeatedly emphasized the pivotal role of wargaming in force design, education, and training. The CMC argues that wargaming will not only inform future force design but could help educate and train future commanders. In the subsequent Force Design 2030 (PDF), the CMC again reinforced the utility of wargaming—ranging from concept refinement to the programming process. Moreover, Expeditionary Warrior, the Marine Corps' Title 10 wargame series, continues to support future concept development, including Future Maritime Operations and the Joint Operational Access Concept. The forthcoming state of the art wargaming center at Marine Corps Base Quantico reflects the service's embrace of wargaming, both as an educational and analytical tool. ...
