Which of the following is NOT one of the recommended war-gaming techniques?

The Bridge method is not recognized as one of the recommended war-gaming techniques within the Military Decision-Making Process (MDMP). The other options—Belt, Avenue-in-depth, and Box methods—are established techniques used to visualize and analyze the possible courses of action. Each of these methods serves a strategic purpose in war-gaming; for instance, the Belt method focuses on assessing likely enemy actions across a specified front, while the Avenue-in-depth method helps evaluate potential threats along a depth of terrain. The Box method is used for a more comprehensive evaluation of options by focusing on critical areas and resources. These recognized techniques facilitate systematic planning, allowing military planners to anticipate various outcomes and refine strategies effectively. The absence of the Bridge method from this list indicates it is not a staple approach in MDMP war-gaming discussions.
