Find out what level offense this is in your state. Likely is not a crime (misdemeanor or felony) but a violation for the first offense.
If it is a misdemeanor, get a public defender and ask for a plea to a lesser charge.
There is likely a standard plea offer for all similarly situated charges/defendants. It may change depending on whether you have renewed your license. If that’s the case you can ask for additional time to renew. That will buy you another court date but give you a chance to get a better resolution if you fix the issue.
Dress like you would for church or a job interview.

This is 100% a political stunt that will go nowhere. If this gets to a trial the jury is active duty military of the same rank or higher than the accused. That’s means the men and women that took over when these people retired will be the jury. These individuals served their careers together.
Even with a court martial not needing a unanimous jury, they won’t be able to field enough Trump supporters to convict that high up the chain.
