Another problem with simulation of chemical or biological agents is the lack of hard evidence on the effectiveness. Lots of anecdotal stuff, but very little to no documentation as to the actual wartime use, effectiveness, conditions. And most of the data I've seen is often "interpreted" depending on who is doing the reporting. It would be a very tough simulation to sell to a group of us when we can't even agree on the effectiveness of 5.56 vs 7.62
