If you are interested in SF in Vietnam, this is a great site with lots of pics sent in from vets of Project Delta. The pics are arranged from 1966-1970, when the project closed. You can see the evolution of gear used.
The interesting thing is that Project Delta recon teams used tigerstripes until the end, for the most part.
The other thing I saw in the pics was several RT members wearing ERDL post-68, so a Project Delta trooper in ERDL is on my bash list. You don't see too many pics of SF troops wearing ERDL.
