Situational awareness is probably the most important thing I learned at Gunsite. Jeff Cooper used a four part color code to teach his concept of levels of mental awareness.
CONDITION WHITE - when a person is unaware of what is going on around them.
CONDITION YELLOW - is being alert to what is going on around you. You don't let people or things get within a perimeter without being aware. This is a relaxed state of general alertness, with no specific focal point.
CONDITION ORANGE- This is a heightened state of alertness, with a specific focal point.
CONDITION RED- In Red, you are ready to fight!

Situational awareness is something I always use when I leave home. I have never had to use my handgun as a civilian in 30 years of carrying. I believe that being aware has saved me serious grief on several occasions.
