Mike, I spent 13 years in SF and never had a kit issued except the tacky one in a green box called an individual survival/first-aid kit. Came in a belt pouch. Survival items were purification tabs, a book of C-rat matches in a sealed plastic bag. That was it! We all made our own survival arrangements, beg, borrow or buy. What kits I came across in the system were pretty much all designed for aircrew issue and we always begged some items from the aviation units. Never the entire vest, just pieces here and there.
I have been out since 1997, so things may change, certainly the uniform has changed to the ACU, which I and glad I never had to wear! Cheers!
