I heard rumors say back in 2003 in Myanmar Chinese SOF from Chengdu Military Region went head-to-head with SFOD and those elite D-boys experienced heavy cansualties (~70 Deaths) and the whole operation failed miserably. Anyone has any info or confirmation? Personally I don't buy this story because Delta is always my favourite SOF in the world.
Wait are you saying that the American Delta Force actually was involved in combat with Chinese special forces? I'm assuming that "SFOD" and "D-boys" is referring to Delta Force. If so, where did this happen? Why?
Personally I think that there is absolutely no way that this story could be true. How could these two forces come to grips? From your vauge language it seems that you could be talking about a training exercise but I'm absolutely certain that American and Chinese Special Forces (especially SFOD) would never train together.
