I believe I talked about this before but here it goes again. When I did Civil War we had two events like this that you are wanting. Rockton ,Ontario in the museum village and in Beaver,PA in the community Park whick was a reclamed gravel pit. We had trails with judges that walked with us. There would be different stations that everyone had to go through. One was civilians, how do you act with them, a snpier who kills off you officer,nco's, cannon hidden in ambush, hospital, ect. We had a mission to find a spy who stole blueprints to a ship.
For WW 2 would be so easy with a tons of things to do Truck convoy gets hit, MG nests, snipers, more cilvilians stuff. ect. This was judged by points. Winners were 1st ,2nd and 3rd place.
This is what some of the BIG units should try to host,I'll help. If you know of a village muesum or park with wooded and open trails ect. This would be a event that would change peoples minds and how the act.
