Widget,
Hey man, good to see another SOF type out there besides me. I've worked heavily with 5th Group on "Iris Gold" and a little with 3rd and 1st group in the sand box. How about you?
Most of the SF units didn't start getting anything until after 2000, and those were and still are almost completely off the shelf or as you say, beg/borrow/steal. But that's the nature of the beast now isn't it?
The NAVSPECWAR guys I've worked with all had a type standardized one, but I have no idea where they come from, probably snagged out of the pilots survival locker.
As far as the ACU's go, it's pretty wierd going to work in your PJ's, but all the pockets come in handy, kinda like all the mods we used to do to our BDU/DCU's that were non-regulation. I just don't like the pattern, it's great for in town, but out in the woods, most of us still wear BDU's of some form. The Marine woodland MARPAT is pretty cool though. It would all be better with no "french wool sock" worn on our heads. You guys that fall from perfectly good aircraft are the only one's that should have those!
Just my $0.02

Cheers,
Mike
