What are some of the most unique Military Reenlistment ceremonies that you have ever witnessed?

A group of us got to reenlist with the USAF Thunderbirds at Eglin AFB, Florida. They were on base for an air show and were doing publicity crap. There were a bunch of us so it wasn't overly personal as experiences go but still very memorable.

My first re-enlistment was in an Army UH-60 over Saudi Arabia. First time I ever flew in a helicopter. As a firefighter we did one in Iraq involving fure trucks and a huge pallet fire in the background. I like the star wars theme one.

Perhaps common place for me to whitness, but airborne aboard a CH-47. We hook them up to the internal comms so they can recite the oath as we fly them around. Had the privilege to do two reenlistment flights in the last two weeks.
