Still none. You messed up and you need to take responsibility. It will stop you from getting a lot of other jobs as well.

Why have you not gotten at least a GED or even a college degree by now? If you are an adult you should have

You are DQ'd for military service of any kind.

For one, any felony is a DQ. More than one is way beyond a total no-go. You can't even get one waived much less more than one. Violent charges (assault) and drug charges are never waived.

Even if you can get a waiver to enlist, you can't waive the requirement to hold a security clearance. If a job requires a clearance you MUST hold that clearance. Period. You cannot qualify for a security clearance of any kind with a criminal record like that. SEALs require a Top Secret clearance. You can't hold ANY job with a clearance -- which is basically all of them. No clearance, no job. No job, no military.

You cannot enlist without a high school diploma or a GED + 15 college credits.

You will not be joining the military in any capacity.

Zero. You cant even join in the first place let alone get the security clearances
