Well said, Joeri!
Doug, you aren't a bad guy! I appreciate that you are there for the shooting, but a lot of us are about putting the "acting" in reenacting. We're just looking for that added dimension.... I've been doing this hobby for 12 years now, and the shooting isn't why I go anymore, unless it promises to be a good scenario. Otherwise, the same old goofiness with people not taking hits, whining about other people not taking hits, bad field discipline, it all starts to wear on you after a while. Perhaps not you though! That's cool, we're all in this for slightly different reasons sometimes.
And I do agree with you, units need to buckle down and learn the proper period commands, signals, and basic tactics. I think dedicated training events are where it's at when it comes to this... you simply can't do a whole lot at the regular events with everyone arriving at different times, wanting to socialize/drink, etc, everything BUT training.
Immersion is awesome when done properly... some events are tactical, some are not. The whole point of an immersion is to get completely into the period, and this is usually done by camping tactically, running round-the-clock patrols, delegating mundane tasks (like digging foxholes, running communications lines, etc). The best one I've been to was at Rensselaer, IN (after I stopped running them there) where we did a 24-hour & stayed in the bunker all night and took turns watching for Amis.
And speaking of civilians, your Spiess (Chris Chalupa) came out a couple years before that at Rensselaer and portrayed an Estonian man who rode around on his bike creating confusion on both sides! He was working for the Germans, but telling the Russians he was working for them (all the while giving them disinformation). The German commander didn't trust him though, which added to the confusion.
