Your Hair
Enjoy the fact that you can get any haircut your heart desires. After all, soldiers are all required to don a buzz-cut. They are free to choose something else when they leave the military, though they will likely resort to the same look.
Scanning Situations
Training involves the art of scanning and assessing any given situation. During their time in the military, soldiers were taught to be alert and vigilant as often as possible. It is second nature for them to scan any location for potential threats the minute they get there. They are not only observant, but they will also act and protect civilians when needed.
