From the Wikipedia article

The high and tight is a military variant of the crew cut. It is a very short hairstyle, characterized by the back and sides of the head being shaved to the skin and the option for the top to be blended or faded into slightly longer hair. It is most commonly worn by men in the U.S. armed forces. It is also popular with law enforcement officers and other public safety personnel. Although "high and tight" is the primary term used in military and law enforcement, the same haircut is sometimes referred to by civilians as a "walker".
