Yeah, basically, the clearance just opens more jobs to you. Also many of those jobs that require a clearance pay more than a similar job without the clearance (sometimes much more), so that's something to keep in mind.
If you're looking for adventure, there also seems to be lots of overseas jobs with govt contractors (L3, E,G,& G, Raytheon, etc) that require a clearance. I've seen several jobs in Iraq and Afghanistan and other places. No necessarily hardcore Aerospace Engineering jobs, but more like they need someone with a clearance and some military experience to do a job.
Operational Exchange--Ha! I knew several people who did that. I even knew a few who were never even told that they were a part of it, until it came time for their next assignment. One guy was an Intelligence officer. He LOVED being an intel officer. He lived, ate, and breathed being an intel officer. When it came time for his next assignment, he had it all planned out where he wanted his next intel assignment to be, and the personnel center came back and said "Oh, no, you're part of this first-term career broadening program. Now you have to go to your "normal" career field as a maintainer." That guy was not happy.
How is it a scam to get engineers to stay in longer?
Regardless, I knew of a guy in almost your exact situation. He had an EE degree, and did 4 or 5 years in missiles. He got out, and got a job down in Albuquerque NM with Boeing, doming some sort of EE work. So it can be done.
Do you have any thoughts as to what kind of industry you’d like to work in, or what kind of work you’d like to do?
