Wargaming Design Workshop – Advanced

21–25 September 2026

NATO Mountain Warfare Centre of Excellence, Poljče, Slovenia

Advances in science, mathematics, and strategic theory contributed to the emergence of military wargaming as a structured method for exploring conflict, testing decisions, and educating military leaders. Since then, wargaming has continued to evolve and remains a valuable tool for military education, analysis, planning, and decision-making.

Combining elements of both art and science, wargaming provides a dynamic representation of conflict or competition in which participants make decisions and observe their consequences within a defined set of rules and conditions. Designers, players, and analysts can gain practical insights not only from a game's results, but also from the decisions, interactions, assumptions, and mistakes made during its execution.

From 21 to 25 September 2026, the Concept Development & Experimentation Branch of the NATO Mountain Warfare Centre of Excellence (NATO MW COE), in cooperation with the U.S. Naval Postgraduate School (NPS) in Monterey, successfully conducted the Wargaming Design Workshop – Advanced.

Multinational participation and exchange of experience

The fourth iteration of the workshop brought together military personnel and representatives from Slovenia, Poland, Romania, the Czech Republic, Austria, and Germany. This multinational participation provided a broader perspective and enabled participants to exchange experiences from different national and professional environments.

Although the NPS instructors were unable to attend in person this year, they remained actively involved through videoconferencing, providing guidance, expertise, and support throughout the workshop.

Applying the principles of wargame design

The workshop began with an introduction to the fundamentals of wargame design, covering the purpose and application of wargaming, the design process, game mechanics, adjudication, player interaction, and the relationship between a wargame and its intended analytical or educational objectives.

Working in multinational groups, participants applied these principles to operational and tactical problems. The emphasis was on translating a clearly defined military problem into a playable and useful wargame.

A significant part of the workshop was devoted to practical work and iterative development. Participants tested their concepts, identified shortcomings, adjusted rules and mechanics, and refined their games based on the results of play sessions.

During the workshop, participants developed three different wargames addressing specific operational and educational requirements.

Cooperation and practical application

The multinational composition of the workshop provided an important opportunity for cooperation and the exchange of experience among participating nations. Designing and conducting wargames together required participants to reconcile different perspectives, approaches, and national experiences while maintaining a shared understanding of the military problem under examination.

The workshop culminated in a multilayer wargame on the final day. This activity brought together the knowledge and skills developed during the preceding days and enabled participants to apply their newly acquired wargaming techniques in a more complex environment.

Throughout the workshop, participants benefited from materials and resources developed during previous iterations of the Wargaming Design Workshop, including access to the SAKAI learning environment.

The successful completion of the fourth iteration once again demonstrated the value of wargaming as a method for military education, analysis, experimentation, and decision-making. By combining theoretical instruction with practical game design and execution, the workshop equipped participants with knowledge and skills applicable to future exercises, operational planning, education, and the development of wargaming capabilities within their organisations.
