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