Probably not the oldest, but never the less...72 y/o...went through the Q course (which at the time all the old guys called it training group) in 1976...no pipeline, no SFAS...we started with PT and swim tests, some 150 or so, around 100 or so made it to Camp Mackall for Phase I...two weeks of intense land nav training, a couple three days of survival training and off to the Uwharrie National Forest for around two+ weeks of advanced land nav, moving only at night, cross-country, alone...less than 40 of us finished that, then off to Phase II...eight weeks of MOS specific training, everyone in my weapons class passed (everyone had passed my demo class, as well), then off to Phase III, which was SF Operations and an FTX. Wasn't called Robin Sage or Gobbler Woods (those were for officers, at the time) and when all was said than done, 28 of us graduated, 14 without having been recycled...off to our groups for language and area orientation, if possible...maybe SERE (very few), HALO and SCUBA for some...can't speak accurately for today's pipeline, just thinking two years or so is a long time to be a student...I was a SGT when I went...most of the class were off the street enlistees (no 18X program) and most of them failed...of the 14 of us that made it without recycling, only three or four had no prior service.
