Systems engineers
My son is a 3rd class in Systems Engineering at USNA.
"Systems engineers design and coordinate large and complex projects known as systems. There are many kinds of systems, and although all are large, they vary in their complexity. A system has many parts that all interact extensively with one another. Often small systems can be part of larger systems. For example, a jet airliner can be a system. So, too, can all of the airplanes owned by one airline. All of the airplanes in a country make up a more extensive system. An even larger and more complex system includes all of a nation's transportation facilities. Systems engineers can work at various levels in the design and coordination of these systems.
Some other examples of systems are water and food distribution networks, experimental manned space flights, and military defense programs. Systems engineers also work on telephone systems, electric power systems, and sewage systems."
I also read that this is one of the fastest growing and highest entry level paying jobs out there right now. They are often confused with IT guys who are called "systems engineers" at their company because they keep the computer systems going. However they dont have an engineering degree and license. Good choice. In the AF they will have a lot of work with UAV's, spacecraft and other cool stuff.
