I don't know him, and I applaud his efforts to get his support guys spun up.
But this goes to the need to have a USASOC or even SOCOM-wide assessment, selection, and training program for enablers. That training isn't dependent upon individual units, or even individuals within units.
Maybe they have something now? I left the SOF world in 2009.
I can only speak for my unit, so things might be different on the active side, but we've started to conduct a "selection" process for new guys and gals.
I put that in quotes because if someone doesn't pass we haven't (and probably never will due to manning) gotten approval to deny them the slot.
We can just heavily recommend they 4187 out of the unit if they don't get up to standard.
Unless something changed, Support wears a maroon beret regardless of airborne qualification status. That started in...99 I think. Again, I don't know if that changed or not.
Still berets. There's a bit of a "legs can't wear the beret" stuff that pops up from time to time, but the NCOs squash that.
