Recruiters do that. I hate to say it, but I've had recruiters come to my rotc course in highschool saying that with giggles. The recruiters will twist things. All they want is for you to join their branch.

Anywho, I wouldn't worry about that too much. If you want to join the marines, cool. I would research it on the webs, but make sure you get a good job in the marines if you go, maybe one that has some extra pay.
