TACTICAL DECISION GAMES
Tactical Decision Games or TDGs are not wargames by traditional definition but are a fantastic low cost resource to conduct decision making, education and orders development.
Typically participants adopt the persona of a leader with a limited amount of information that sets the scenario. This includes the situation, terrain, their mission and their forces. The facilitator or narrative then usually describes an event that creates a dilemma for the participant to solve in a given time frame. The format for the solution is usually a standard, but short, orders format.
