Dear Mr. Chappel,
Thank you for posting your request on History Hub!
We suggest that you contact U.S. Marine Corps officials at the facility where you were scheduled to attend the Marine Recruit Training Depot (MRTD) and ask if a record of your attendance, reporting, and then declining enlistment under the Marines Delayed Entry Program exists.
You may wish to review Marine Corps, Delayed Entry Program for more information.
We hope this is helpful.
