This UPT class went through my T-38 squadron at Vance in 2013. Unlike what the press "reports" show, this was actually a bunch of young Lieutenants' reaction to the AF's "health and welfare" witch-hunt that demonized anything that was remotely deemed offensive by pretty much anyone, anywhere. This was the inspection where, I kid you not, the Wing Commander at Wright-Patt had the nose art on the two combat vet WWII bombers in the USAF Museum ("Shoo Shoo Shoo Baby" and "Strawberry Bitch") covered up while the "inspection" was taking place, just in case the temperature of the water broke in the direction of that being found "offensive" (and fortunately, it wasn't).

They'd had a tough time getting other class patch ideas approved by the PC police on base, and decided that to thumb their nose at the ridiculous atmosphere in the Air Force, they'd take it as far to the other unicorns-and-rainbows direction that they could go. While the idea of Lieutenants flipping the bird to the PC establishment is well in line with the warrior traditions, the methodology they chose wasn't really on-point, to put it mildly. Predictably, the patch was approved by the AF leadership there at Vance. The Squadron Commander of the Student Squadron at the time is an old bud of mine (and legit old-school fighter pilot type), and his reaction to it was, "well...if that's what they want to wear on their shoulders, they'll regret it soon enough."
And regret it they did, especially after these media articles made it out and more and more calls started flowing in to Vance AFB asking to talk to students in this class. They learned a tough object lesson in second-order effects, that the rest of the non-hipster world doesn't find "irony" as ironic as they thought it would be.
When they graduated T-6s, the Flight Commander of the T-38 flight they went to (a former fighter Major) ordered the students in that class to not wear it, and they didn't. To a man, all of the students in that class that I spoke to (on the T-38 side of the house -- can't speak for the herbivores over in the T-1 squadron) seriously regretted doing it. On their own, they designed and made a new class patch; I don't think they ever went through any approval process for the "replacement" patch, but as I recall it was a pretty cool patch and, thus, no instructors ever thought to make an issue of it.
