The MOS code "0311" refers specifically to riflemen in the United States Marine Corps—a role known for its rigorous training and emphasis on discipline and teamwork. Many federal agencies actively recruit military veterans due to their experience and skills developed during service.
The U.S. Secret Service is a federal law enforcement agency under the Department of Homeland Security responsible for protecting national leaders and investigating financial crimes.
