Dear,  
 
This is in reference to your application for correction of your naval record pursuant to Title 10, United States Code, Section 1552.  After careful and conscientious consideration of relevant portions of your naval record and your application, the Board for Correction of Naval Records (Board) found the evidence submitted was insufficient to establish the existence of probable material error or injustice.  Consequently, your application has been denied. 
 
A three-member panel of the Board, sitting in executive session, considered your application on 29 September 2020.  The names and votes of the members of the panel will be furnished upon request.  Your allegations of error and injustice were reviewed in accordance with administrative regulations and procedures applicable to the proceedings of this Board.  Documentary material considered by the Board consisted of your application, together with all material submitted in support thereof, relevant portions of your naval record and applicable statutes, regulations and policies.  In addition, the Board considered the advisory opinion contained in Headquarters, U.S. Marine Corps (HQMC) memorandum 1920 MMSR-2 of 4 December 2019; a copy of which was previously provided to you for comment.  
 
On 4 February 1980, you enlisted in the U.S. Marine Corps Reserve Delayed Entry/Enlistment Program for 6 years.  On 5 August 1980, you entered active duty in the U.S. Marine Corps, and you were discharged on 5 July 1994.  On 6 July 1994, you entered the U.S. Army Reserve, and you were separated on 17 August 1997.  On 18 August 1997, you entered the  Army National Guard, and you were separated on 5 August 1999.  On 6 August 1999, you entered active duty in the U.S. Marine Corps, and you were retired on 30 November 2007. 
 
 You requested that your current AFADBD (Armed Forces Active Duty Base Date) of 1 April 1983 be corrected to reflect 4 February 1980; the Board, in its review of your entire record and application, carefully weighed all potentially mitigating factors, to include your assertions.  However, the Board concluded that you were not on active duty from 4 February 1980 to 4 August 1980 while you were in the Delayed Entry/Enlistment Program.  Furthermore, the Board was unable to determine the dates of active duty time spent in either the U.S. Army Reserve or the  Army National Guard.  In this connection, the Board substantially concurred with the comments contained in the advisory opinion. 

Regarding your request for a personal appearance, the Board determined that a personal appearance with or without counsel will not materially add to their understanding of the issue(s) involved.  Therefore, the Board determined that a personal appearance was not necessary and considered your case based on the evidence of record. 
 
It is regretted that the circumstances of your case are such that favorable action cannot be taken.  You are entitled to have the Board reconsider its decision upon submission of new matters, which will require you to complete and submit a new DD Form 149.  New matters are those not previously presented to or considered by the Board.  In this regard, it is important to keep in mind that a presumption of regularity attaches to all official records.  Consequently, when applying for a correction of an official naval record, the burden is on the applicant to demonstrate the existence of probable material error or injustice.   
 
Sincerely,
