“Say Again”
You know you’ve run into a soldier if they say “say again” instead of “pardon me” or “excuse me”. Those who once served in the military won’t drop this habit after being released from serving.
Finding The Exits
Soldiers are trained that upon walking into any situation, they always need to find and know where the exit points are. This habit will stay with a soldier for their entire lives; you can be sure they know every possible exit in case of an emergency.
