There is a lot of interest in Force on Force (FOF) recently. But to me the way they appear to be run (I have not attended any) involves and open area with nothing to trip over, plus soft ground not concrete to fall on. I can understand why that is done, but guess how realistic. I think about the places and situations, where I might be attack. Not that many given my life style, but still they seem to mainly involve places where movement is limited and a fall could easily result in injury or restrict ones ability to respond to the threat. I know you have studied many gunfights. I am primarily interested in the civilian context. My questions are: In the gunfights you have studied, what generally was permitted in the way of movement? And what would have been wise in regard to movement?
