The Navy Enlisted Classification (NEC) system supplements the enlisted rating structure in identifying personnel on active or inactive duty and billets in manpower authorizations. NEC codes identify a non-rating wide skill, knowledge, aptitude, or qualification that must be documented to identify both people and billets for management purposes.
For example, if a Navy police officer ( MA -- Master at Arms ) receives specialized training as a K-9 Dog Handler, he/she would be awarded NEC MA-2005. From that point on, the sailor could be assigned to Navy law enforcement duties involving military working dogs.
