Thank you, Dr. Coopersmith. As the article notes, mil sims have had varied success. Larger scale efforts generally being less useful. The best effort in my experience was a high value targeting cell simulation that SAIC in McLean had put together 15-20 years ago, back when mobile missile launchers, WMD sites, and Osama bin Laden (etc) were the rage. Their lash up was a combo of systems sims, a simplified targeting/combined air ops center (CAOC), and human players with operational experience a la a wargame. The main drill to seek accelerators/simplifiers for the targeting cycle (was then FFTTEA, probably has evolved since). We routinely built engagement and mission scenario M&S to inform investment decisions (make, buy, upgrade, etc) at the Naval Air Systems Command's Warfare Analysis group but these were not for training but for plausible systems and operations effectiveness assessments. 6DOF physics models are rarely needed for most of an entity's movements, so some computing power can be saved there, but it is critical to not skimp on the environmentals - atmospheric, terrain, RF propagation, and systems reliability. Even if these environmentals are credible, simulating the heat, stress, and confusion of the battlespace may be a challenge. Good sims need to incorporate signal noise and systems failures. That said, while I applaud initiatives to improve training and preparedness, I have never bought into Adm. Owens' apocryphal "lifting the fog of war" and the premise of network centric warfare - the military IoT will be more of a vulnerability than an advantage as time goes on. In the infospace, adversaries do not need a sophisticated industrial base - millions of IT smart people around the world to mess with our powerpoint engineering concepts. Thinning, perhaps, in some regards, but not "lifting." Those 90s IT-centric ideas are alive and well in DoD - OV-1 charts laden with lighting bolts remain common. One new sim we do need is for the offense and defense sides of long-range guided missile salvos, particularly at sea.
