An active memory helps, but it has gotten a bad name called flashbacks. I am now trying to be uncured of that to the extent I can apply the skill to current environments. This article and website will help.
My son was a member of Marine Presidential Security Forces, and is now with the Federal Protective Agency. I remember one of his sound bites was, “Always be courteous, always be professional, always be prepared to kill anyone you meetâ€.
I’ve never been in the military but I’ve always been interested in knowing what was gone. I’ve also worked some jobs that really required situational awareness like a sawmill.
