I find the definition of SA given in the post somewhat flawed:

Situational awareness is the skillset and related state of mind that allows one to effectively perceive the world around them.

That's fuzzy and descriptive rather than defining, and seems to broadly describe what I would call being perceptive. If I had sharper eyes, would my SA be better? Or would that not count as a skill? Is the ability to concentrate on something part of SA? How about eidetic memory, balance/kinesthesia, absolute pitch, pattern recognition, psychological resilience, spatial visualization, or eye adaptation?

In my opinion SA should properly be defined prior to any sequence posts or, if that would be impractical, the term should be tabooed.
