You cannot own a firearm with a dishonorable discharge, which is the most severe discharge there is. However, a "less than honorable" is not the same as a "dishonorable" discharge. If the discharge resulted from a court martial, and the service member was convicted of a crime that would be a felony (punishable by a year or more in prison) then you should consult an attorney for legal advice.
The only thing you can do is appeal your discharge.
A dishonorable discharge is the most severe form of punitive discharge from the military and can only be imposed by a general court-martial. It is reserved for the most serious offenses. A bad conduct discharge is considered a less severe form of discharge and can be given by a special or general court-martial for serious misconduct.
