In sports they like to talk a lot about home field advantage, and often use it as a justification for poor performance. While the focus is often on the psychological impact, I think it reflects poorly training situational awareness.
When you breakdown disadvantages of not playing on your home turf it is either changes in the visual or auditory stimuli that the fans create or the physical properties of the field itself. Turf or grass? A blue vs. green field. Going from a warm, sunny environment to a cold snowy one?
These disadvantages are functions of situational awareness systems:
1. Visual
2. Auditory
3. Vestibular
4. Somatosensory
Maximizing the function and utilization of all the situational awareness systems and adding chaos is key for readiness and maintaining performance at an elite level in any environment.
As tactical operators you know this well because there is no such thing as home field advantage for you. You are elite because you have elite skills, strength, and capabilities, but also because you can execute at the highest level in any environment.
You depend heavily on your situational awareness systems, train to maximize each one of them.
