Chockstock,
I'll do you one better: I'll explain how a security clearance can get you a job.
First, what is a security clearance? Pretty simple, its the US Government telling you (and the world) that they trust you enough to view secret information dealing with National Security. Get a Secret Clearance, and you're allowed to look at secret information, such as technical specifications, troop details, stuff like that.
Getting a Secret Clearance is pretty simple (and is offered to you during your attendance at an Academy because you have the opportunity to attend Secret Level briefings and events. Not sure if it is REQUIRED (all you current cadets and folks more in the know, help a brother out here!). To get one, you need to fill out a form detailing past history and circumstances (questions like, "have you ever been arrested? Ever done drugs? Ever have money problems?"), proving to the government you are trustworthy.
Now, there are levels of security higher than SECRET, such as TOP SECRET (and stuff even higher). To get one of THOSE clearances, the Government will perform a background check on you beyond just looking at your survey responses. Government agents will actually ask you for REFERENCES they can interview, and they WILL interview them (so be careful who you put down. Coach or teacher? Good choice. Life long buddy who will spill the beans about the time you all went cow tipping and broke that farmer's fence, just because he still finds the story hilarious? I'd keep his name off the list.
) Your life history WILL be examined, thoroughly! I mean, were not gonna just hand you the keys to the alien saucer in Area 51 without making sure we could trust you, would we? Ooops, shouldn't have said that!
Also, clearances are only good for a limited time. 10 years for SECRET. 5 years for higher. EACH time, to have to update and resubmit your form, and EACH time you have to go through an investigation.
Now, how can having a clearance help you land a job? Well, there are lots of industries that work with the government on "classified" issues. From engineers who design new weapons and platforms, to guys building a new Nuclear sub, to folks who even are designated to taking out the classified trash! This companies NEED people who have security clearances. The higher the job security clearance required, the more they want you, because those high level clearances are hard for people to get, and cost a lot of money TO get (due to the amount of investigation involved).
When I retired, i had a VERY high security clearance level. And my clearance had just been re-approved for 5 more years less than a year before I retired. Put that fact front and center, in boldface, on my resume. Can't tell you how many company HR people saw just THAT fact, and interviewed me for the job on the spot!
Now, I work in the Pentagon on the F-35 as a Defense Contractor. And having a security clearance was a large factor in why I got the job. (My dashing good looks, strong masculine profile, wind swept hair, debonair - devil may care attitude, and bright shiny teeth helped a little as well!
