I'm on normal, and I haven't really been annoyed by it. It happens from time to time, but you do need to keep out of spitting distance when a thin man is around.
This panicing sounds like it causes a few problems. It's not continually annoying is it? Can you bolster your troops resolve with sing a longs or banners or something?
From the sounds of it on here they can come across as a bit wimpy. It's annoying when games take control out of your hands and crazy shit happens, like Marv goes loco when a jam sndwich lands next to him.
