Final answer:
In military science, one commonly used template to graphically depict enemy COAs is the Decision Support Template (DST). Other graphical templates utilized in military science for depicting COAs include the Event Template, the Synchronization Matrix, and the Time-Phased Force Deployment Data (TPFDD) Graph.
Step-by-step explanation:
In military science, one commonly used template to graphically depict enemy COAs (Courses of Action) is the Decision Support Template (DST).
The DST is a visual tool that helps military planners analyze different courses of action by depicting each COA as a separate branch or timeline. Each branch represents a possible action the enemy may take, and the planner can add specific details and variables to each branch to assess its feasibility and potential outcomes.
Other graphical templates utilized in military science for depicting COAs include the Event Template, the Synchronization Matrix, and the Time-Phased Force Deployment Data (TPFDD) Graph.
