Finding The Exits
No matter where a soldier goes, he or she will be paying attention to where the emergency exits are. In their minds is the full playback of a situation that might not ever happen, and that situation includes having to exit the location (movie theater, school, ballpark) as quickly as possible.
Right Hand Free
Always, always, always keep your right hand free! You’ll notice soldiers with their partners on their left hands, simply because their right hand is their dominant hand and you never know when you might need it in an emergency situation.
