BUSAN, SOUTH KOREA - JULY 25: (EDITORS NOTE: Image has been reviewed by U.S. Military prior to transmission.) In this handout from the U.S. Navy, sailors prepare to man the rails aboard the aircraft carrier USS George Washington (CVN 73) as the ship departs on July 25, 2010 from Busan, South Korea. The United States and South Korea are conducting the combined alliance maritime and air readiness exercise 'Invincible Spirit' in the seas east of the Korean peninsula from July 25-28, 2010. This is the first in a series of joint military exercises that will occur over the coming months in the East and West Seas. The exercise, the first joint drill after the sinking of South Korean warship in March 2010, is took place for four days and has drawn condemnation from Pyongyang.

The Navy Enlisted Classification (NEC) system, of which the NEC coding system is a part, supplements the enlisted rating structure in identifying personnel on active or inactive duty and billets in manpower authorizations. NEC codes identify a nonrating wide skill, knowledge, aptitude, or qualification that must be documented to identify both people and billets for management purposes.

For example, the rating for a Navy Hospital Corpsman is HM. However, just holding the rating of HM does not tell us what specific medical job that person performs. However, if he/she held the NEC HM-8407, we could look at the below list and find out that the person is qualified as a Radiation Health Technician.
