Is my total active federal military service date supposed to match my DATE INITIALLY ENTERED UNIFORMED SERVICE?

Your total active federal military service date (TAFMSD) does not necessarily have to match your Date Initially Entered Uniformed Service (DIEUS). The TAFMSD reflects the total time you have served on active duty, while the DIEUS indicates the date you first entered any branch of the uniformed services. If you had breaks in service or transitioned between components (e.g., active duty to reserve), those factors can lead to discrepancies between the two dates. Always refer to your official military records for accurate information.
