Final answer:
Sailors seeking financial aid for education typically utilize the Department of Veterans Affairs via the GI Bill, and should also complete FAFSA for additional support through the Department of Education.
Step-by-step explanation:
Sailors applying for financial aid for off-duty education may obtain assistance from a number of governmental agencies. Among these, sailors can utilize the Department of Veterans Affairs, particularly through the GI Bill, which offers assistance with tuition, books, supplies, and living expenses for veterans returning to school or attending college. It is also advisable for service members to understand how to complete the Free Application for Federal Student Aid (FAFSA) provided by the United States Department of Education. This could further unlock federal student loans, grants, and work-study programs which are crucial for covering postsecondary education costs.
