Youre correct. Not alot of Americans speak Afghan.
Like I said, they use the local population heavily. They may hire interpreters, most likely NA people. They may also bring civilians along to interp.
We had Somoli-Americans with us in Mogadishu, civilians contacted by the DOD. Some were unlucky enough to be caught in firefights with us as well! During the Oct 3-4 battle, we gave the interps sidearms, totaly against policy, but it was so bad that night we didn't know if we were coming back anyway.
The way it should work is;
The Spec Ops get intel and chopper in to confirm. They radio for airstrikes from gunships or fighter-bombers and guide in the strike.
If its a populated area, they may fast-rope in and raid a target building like youve undoubtedly seen on TV. That is a high-risk operation, but we don't bomb or shell population areas.
Now I think you see why I hail these guys as the best of the best. Its a job more dangerous than a NYC taxi driver!
