Part of the enlistment process includes going to the MEPS for a physical and swearing in to the DEP and filling out part of the contract (DD form 4). People who have taken these steps can still get out of the DEP using methods described above.
Eventually a persons time in the DEP ends and the transition to active duty for training (basic training) begins. On the date when a person is scheduled to report for basic training, they will normally be instructed to return to the MEPS and swear in a second time while they sign the last sheet of the military enlistment contract (blocks 20, 21, and 22 of the DD form 4/3 ) which states that the person wishes to be discharged from the Delayed Entry/Enlistment Program (DEP) and enlisted in the Regular Component.
Up until that final point of the second swear in and signing of the last page of the contract, people have been able to get out of the DEP by simply refusing to go. Once a person has sworn in the second time as part of shipping out they may still be able to get out of the military, but it will involve much more time and energy. People who believe they are in this status can contact a GI Rights Counselor at 877 447 4487 to determine what options they have.
