Jrotc instructor DUI

A current JROTC instructor pled guilty to a DUI. Will this make them ineligible to continue in this position when their next NAIC (is that right acronym) rolls around?

Depends. What were the conditions that the court imposed? Has he/she met those requirements? How recent was the incident? What about changes in alcohol consumption such as counseling, changes in consumption, why, when etc. You probably know the drill so impart this to that individual.

I don’t know anything other than they entered a guilty plea for a DUI charge.

One DUI does not kill a clearance. A JROTC instructor, a retired/former military member, normally does not maintain a clearance anyways.
