Anyone saluted the wrong rank working on a Joint Base?

I saluted a Japan Air Self-Defense Force staff sergeant at Ali Al Salem Air Base in Kuwait.
We all laughed.

When I served in Schweinfurt Germany, I was a part of 1/4 Cav and our Distictive Unit Insignia looked like captains bars. It had a blue center piece with silver bars on the outside. As a PFC in BDUs, I received many a salute from all ranks, they’d look down and see PFC rank on my collar and usually grumble as they walked on by.

Wrong rank in basic training. I was returning from sick call and had my hands full when I see our First Sergeant approaching. I wanted to be on top of my game so I shifted my items in my hand and gave a salute as he was passing. I gave the greeting and must have called him sir. His response was something like, "I'm the First Sergeant dumbass." Thre things we don't forget that we would like to not remember.

Graduation day Parris Island a couple of us 18 year old grads were hanging around waiting to be told our next move. One of our platoon guys was about 24/25 and slightly overweight with a naturally bald head and chubby cheeks. He must have been saluted a dozen times that day, not just buy boots but anyone who came along. Needless to say he ate it up and we busted chops all day.

I don't think I have saluted the wrong rank, but I have been saluted by others that thought I was an officer. (retired as CPO-E-7)
All members of Coast Guard wear a White Combination Cover, which confuses the Navy.
The 1st time it happened I was fresh out of boot camp, My 1st ship went to San Diego, I was walking the pier and a Navy PO1, saluted me, I thouht I missed an offier, and was stressing until I realized he was saluting me.
a 2nd time that sticks out, I was at a Navy School in VA as an PO2 (E-5) Was Telling a Navy Chief about it, he didn't believe me, I put on uniform to wear Combo Covers and we walked around base. Received Several Salutes, he was embarrassed for the Navy.

Happened a lot of other times, over my 20 yrs, I'd educate those that did, and move on.

Not with anyone in the other branches of our military, I made it a point to learn all the rank's of enlisted and officer in each branch. But I did salute a British Sergeant Major mistakenly, due to my miss recognition of his rank on his shoulder. He said thanks and that he does not rate a salute.

A navy "Chief" is an E7. Senior Chief is E8, and Master Chief is E9. How does anyone mistake Chief Petty Officer rank insignia for officer insignia while being close enough to salute? If you meant Chief Warrant Officer rank insignia, then you were correct saluting even if they didn't expect it.

I was often soluted by lower-enlisted Navy Personnel when I was a SPC at Fort Sam Houston. I would just laugh, explain I was an E4, and be on my way.

Happened on JBA and when deployed to PSAB or AFG

I had that happen in reverse. I was stationed on an Army post (Hunter AAF), and here's me a lowly A1C heading off to work when I passed a couple of Army Sergeants. As I approached, they stood at attention, saluted, and said "good morning, sir!".
I was taken aback for a second, looked around for the officer I thought might be behind me. When I didn't see one I returned the salute and said "good morning", and continued on to work. Interesting way to start the day.
