The Career Planner in any battalion has one job: keep Marines enlisted. Usually, as your EAS date looms, you are likely to be approached by these institutional agents to talk over options for re-enlisting (should you be considering it). They can authorize bonuses and negotiate incentives for you to stay onboard.
Maybe you want a new duty station? A new MOS? Perhaps a few extra bucks will be enough to grease the palms into sticking around (or returning). For some, there is no price for the sweet sound of freedom.
Whatever you choose, just remember that the GI Bill is an incredible benefit and allows you a second wind to do literally whatever you want with your life.
