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.
Below are the NECs for the STEELWORKER community area:
SW-6010 - 6021
Note: Personnel attached to the Reserve Naval Mobile Construction Battalion (RNMCB) are awarded NECs SW 6010 and SW 6021 based on the recommendation of individual Commanding Officer, RNMCB and approved by Commanding Officer, Naval Reserve Personnel Command (NRPC) in lieu of completing applicable course.
