Dear : This letter 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 the entire record, 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. 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 issues involved. Therefore, the Board determined that a personal appearance was not necessary and considered your case based on the evidence of record. Although your application was not filed in a timely manner, the Board found it in the interest of justice to waive the statute of limitations and consider your application on its merits. A three-member panel of the Board, sitting in executive session, considered your application on 8 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. The Board carefully considered your request to correct your record to reflect that you attended and completed training at Marine Corps . The Board considered your contention that you attended the Marine Corps in , as a member of Marine Corps Reserve Motor Transport Battalion, , However, no record of your attendance at the school was documented in your official military personnel file (OMPF). The Board noted that there is no evidence in the record, and you submitted none to substantiate your claim. The Board concluded that, since the burden is on the applicant to demonstrate the existence of probable material error or injustice, you failed to meet the burden of proof necessary to establish an inaccuracy or injustice warranting modification to your OMPF, or issuance of a completion certificate from Marine Corps . 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 the 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,
