A well developed situational awareness is indeed important. For the person that is armed, well any person for that matter, in avoiding danger if at all posible. For the person that is armed, to heighten their senses and to prepare for, "for fight or flight". For those who refuse to arm themselves, when there is no avenue of escape, they are out numbered and un armed, they can be perfectly
aware that they are up a $@!# creek without a paddle and they should take that opportunity to
their fourth point of contact goodbye.
