The paper describes a system, known as TDSS, constructed to allow the wargaming of Courses Of Action (COA). TDSS employs agent-based distillation (ABD) technology, being built atop the CROCADILE simulation engine, representing battlefield assets as independent entities in a 3D environment. An experimental framework involving twenty five (25) Australian Army junior commanders, in the same manner that Tactical Exercises Without Troops (TEWTs) are assessed within the Australian Army, was developed and used to test the new tool against traditional means of wargaming. COAs were wargamed using the traditional approach as well as employing TDSS. User and Instructing officer evaluations were elicited, contrasting the two approaches. The results from the experimentation show that a clear and significant increase in military insight and understanding is gained through the use of the new tool. Similarly there was a significant increase in the confidence in results obtained through the use of the new tool, primarily as a result of the ability to data-farm a course of action as well as to clearly visualise the flow of action. In addition, there was a significant reduction in the time taken to conduct the wargame. 1.</p></div><div id="citations" style="margin: 0px; padding: 0px; border: 0px; font-weight: normal; font-style: normal; font-size: 12px; font-family: arial, sans-serif; vertical-align: baseline; color: rgb(0, 0, 0); font-variant: normal; letter-spacing: normal; line-height: 16.799999237060547px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"> </div>
