To add to this, in John Plaster's book, Secret Commando's: Behind Enemy Lines with the Elite Warriors of SOG, some Team Leaders limited their teams to wearing NVA uniforms complete with Chinese weapons and gear. Pretty smart move in my opinion considering the nature of their missions and how far behind enemy lines they would be.
By the way, a great book to read if any one is interested. Unlike some of the Special Forces / "Spook" books that are out on the market covering that time period, Plaster's books covering SOG are very credible and interesting, especially since he was actually apart of the program and has been honored by the US Army's Special Operations Command for his contributions in recording the history of Army Special Forces.
