Code Yellow is threat awareness. Known as 'switched on',

this state of perception allows 360 degree peripheral

awareness of environmental vulnerability. For example the

awareness of secluded doorways, entries etc. and the

psychological dangers of untested physical artillery (selfdefence

techniques that have not been pressure tested)

adrenal dump, attackers rituals etc. Initially, Code Yellow is

similar to commentary driving, where you talk through and

describe, as you drive, everything you can see around you.

Similarly, as you walk, run a subconscious commentary of

everything that is happening in your locale, ultimately, with

practice, managing the same without verbalising the

commentary.
