The oath you take to become a member of the D.E.P. does not make you legally obligated to go to Basic Training and be in the United States military. Recruiters are under pressure to fulfill their obligation to the military, often failing to inform new recruits of their rights. In most of the calls CCW answers relating to the DEP, the client's recruiter has failed to follow the regulation stating that they cannot exploit you. The Army (the largest branch of the military) has regulation prohibiting recruiters to:

“threaten, coerce, manipulate, or intimidate D. E. P. members, nor may they obstruct separation requests.
(USAREC Reg 601-56§3-1.c) ...At no time will any recruiter tell a D. E. P. enlistee he or she must ‘go
in the Army or he or she will go to jail,’ or that ‘failure to enlist will result in a black mark on his or her
credit record,’ or any other statement indicating adverse action will occur if the applicant fails to enlist.”
(Exerpted from USAREC Reg 601-95 §3-1.b.; see also USAREC Reg 601-45 §2-3.h.)

If you decide not to join the military after signing up with D.E.P., you are not legally required to have any further contact with your recruiter. You may want to go out of town around your original date of enlistment to avoid pressure from your recruiter. You are not obligated by law, or any authority, to answer the door, the phone, or go anywhere with your recruiter. If your recruiter pressures you or tells you that you will be in legal trouble if you do not show up for Basic Training, refer them to the military regulations. So you don’t have to go. If you don’t go, you are not in the military. It’s as simple as that.

But why would my recruiter pressure and coerce me, or lie about my rights?

Recruiters have a job to do. They have a certain quota they need to meet each month. If they don’t meet this quota, their careers are in jeopardy. It is in their best interest to get you to sign up, graduate if necessary, and go to basic training. At that point, you count towards a recruiter's quota.

Remember. All you have to do, is not go.
