ROTC programs produce Unrestricted Line Officers. Period. That means officers who can be put into combat when needed. While there are jobs that such officers can take which may not require combat, you never know when you'll end up in a combat zone. Think of the truck drivers in the Iraq war who ended up in combat, getting wounded and being take prisoner. Not saying don't try, but it does seem unlikely. Enlisting, where one can sign a contact for a particular job before going in, might possibly be an easier alternative.
