security clearance

What type of security clearance does 1812, m1a1 crewman require? I have not held anything from my recruiter or meps I was just wondering because I have a misdemeanor from 4 years ago and I'd hate to get denied. Hopefully I wouldn't since I have been upfront and honest about it from day 1 but I was just wondering. Any replies will be appreciated, thank you

MOS 1812 does not require a security clearance, however, all Marines are required to complete a NACLC at enlistment, which if favorably adjudicated, results in secret security clearance eligibility.
