Quick question about UCMJ articles on an officer.

While driving just off base today a truck improperly switched lanes before getting to the gate, almost hitting my bumper. I gesture towards the far right lane with my hand. The driver of the truck then follows me to where a park, parks improperly in a parking spot, gets out of his truck to yell at me and say that I gave him the bird (which I didn’t). All while I’m in my car just chilling after parking. He is an O-4 and I’m an E5. Does UCMJ article 89 or 134 apply?
