Each of the armed services brings particular expertise to the table. This mission could probably be accomplished by a single service, but certainly not as well. However, like an athletic team, we're able to fit those with strong skills in particular areas in the places they're best suited. That includes the contributions of reservists to the operation. In the 'one Navy' concept, I just happen to have an 'R' after my name.
Reservists have special job skills the military can capitalize on.
Ultimately it just brings more back to the mission. Under an agreement between the Navy and the Labor Department's Bureau of Apprenticeship and Training, there are apprenticeships available in 78 ratings and 74 trades. It is an excellent program to set up something that you can use once you leave the Navy. Some colleges offer credit toward an associates degree for completion of an apprenticeship program. The program gives Sailors the opportunity to meet the requirements to participate in state licensing examinations.
