On the Marine side, you can look at PLC. On the Navy side, NUPOC, but that will steer you towards nuclear power vice Intel. I'd recommend you just finish strong academically, get in shape, and prepare to start an OCS application with an officer recruiter.
What do you mean "over for them"?Typically, Navy officer recruiters will tell you that you can start The OCS conversation at some point during your junior year. When you actually start the application...that's over to them.
