“The overwhelming majority of USMCR officer accessions (76 percent) obtained their commissions through OCS or the Marine Corps Platoon Leader Class (PLC).

PLC is a split-training program in which candidates normally attend officer training in the summers after their junior and senior years of college.”

So if he did six weeks, is that just one of two periods? It was my understanding that OCS was 90 days (hence the term 90 day wonder). If that's the case, then that doesn't explain why French lists 1977 and 1978 if he only completed one of the training periods.
