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 1 October 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 Navy Personnel Command memorandum 1430 PERS 8031/0032 of 21 January 2020 and Navy Department Board of Decorations and Medals letter 1650 NDBDM/102-20 of 11 August 2020 and your response to each opinion. You requested the September 2017 (Cycle 236) E6 advancement examination be revalidated and the March 2018 (Cycle 239) E6 advancement examination be invalidated. 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 the modification of your original end of tour award ending October 2017 to the ending period of August 2017 which caused your advancement to E6 effective 16 December 2018 to be modified to 16 June 2018 was invalid. The subsequent correction of your award ending date to October 2017 and advancement to E6 effective 16 December 2018 is appropriate. In this connection, the Board substantially concurred with the comments contained in both advisory opinions. 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. 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,
