Mr Evil is absolutely right on this one.
The biggest role of US Special Forces is to train indigenous forces. They did this in Iraq pre-invasion in the largely unheard of FIF. (Free Iraqi Forces if I remember correctly).
As you see in the photo, they wore the older 'chocolate chips', and the VietNam era flak jackets.
My own contact with them was rather, er... limited... A few of them after having driven out some Saddaam loyalists with Coalition assistance decided to engage in a bit of looting. Where this took place, I wasnt privy to, but they made it to the prison camp I worked at in May '03. They were still in their chocolate chips, and were going to be thrown into GenPop (general population) with a bunch of the guys they'd been fighting against! So we at least did them the favor of changing them out of those uniforms and into the same style jumpsuit we gave out to those who did not already have decent clothes.
I ended up keeping an FIF patch off of one of their uniforms, as well as an FIF ID card (that one was an accident though) that an FIF Colonel told us was no good.
We think he was just so disappointed at what they had done, that he wanted them to just go away and pretended they werent really FIF.
So back on subject: A USMC Force Recon team, or SAS team leading a group of MEA not outside the realm of possibility.
You could have them leading a distruptive force within a nation occupied by the PLA in prep for the arrival of conventional forces. Providing the leadership and logistics necessary to engage a superior force.
Take a look at the book 'Roughneck nine-one'. US Army Special Forces supported by several truckloads of Kurds.
The SF's would sit up on this hill shooting up military convoys on an Iraqi highway, and send the Kurds out to subdue the survivors/capture prisoners. Problem is the CAS bombed some of the Kurds.
The idea cup runneth over...
