Your Hair
Civilians can choose whatever haircut they would like to wear, but soldiers all get the same buzz-cut. However, after leaving the military, they can get whatever haircut they want, but most just stick to the kind that they have gotten used to.
Scanning Situations
Right from the start, scanning and assessing situations is something soldiers are trained to do. They are always watchful and alert to anything out of the ordinary. Also, they will definitely act if needed. For that reason, don’t get surprised if your soldier partner quickly scans a family picnic at the park, a concert or even a room.
