I don’t know if this relates to the specific class you mentioned, but it’s about the right time period. A study was done on the higher dropout rate and it ended up being attributed to one new officer who was a real hardass.
“The report also touches on a period of heightened attrition seen at BUD/S during 2021-2022 that started shortly after Basic Training Command, which oversees BUD/S, had a change of command in the fall of 2020. Beginning with Class 346 in January/February 2021 attrition during the first three weeks of 1st Phase began to “noticeably increase beyond historical averages,” the report states.
It adds that “attrition due to candidates dropping on request during weeks 1-3 of 1st Phase rose during 2021/2022 to 48 percent and 49 percent respectively from the historic average of 30 percent.” This heightened attrition continued throughout the course of an unnamed officer being in charge of 1st Phase, until returning to normal levels by Classes 354 and 355.
Exit interviews of those classes with heightened attrition rates showed that 91% of students who didn’t make it cited “physical limitations or a lack of motivation” as the reason for quitting and 8% cited specific injuries. The leadership of BUD/S, however, attributed the heightened attrition of Classes 350-355 to COVID-19, an increased intensity in how the curriculum was administered, including the addition of ruck runs to training, and “overly enthusiastic class leadership creating extra work at the expense of rest.” In other words, the student leaders of BUD/S classes were pressuring fellow students to drop out, and putting demands on their fellow classmates above and beyond the BUD/S curriculum.”
