Your Hair
While civilians can have any kind of haircut they wish to wear, soldiers don’t get as much freedom when it comes to choosing hairstyles and they all get the buzz-cut. After discharge, they can get any kind of haircut that they want, but most choose what they are used to.
Scanning Situations
Right from the beginning, soldiers get training on scanning and assessing situations. They watch out for anything unusual and they are prepared to act on it if need be. Therefore, don’t get surprised when your significant other who was in the military starts scanning the room, or a concert, or basically any place they are in.
