What is the discharge form for the merchant marines?

The discharge form for the merchant marines is known as the "Merchant Mariner's Document" (MMD) or "Merchant Mariner Credential" (MMC). This document serves as proof of a mariner's qualifications, including their training, certifications, and sea service. Upon completing their service, mariners may also receive a "Discharge Book," which records their time at sea and can be used for future employment within the maritime industry. These documents are essential for demonstrating competency and ensuring compliance with maritime regulations.
