The problem is the NPR reporter was nowhere near the missles and never saw them.
This all goes back to a botched Reuters wire story on the whole thing (which Rush Limbaugh ended up seeing and then talking about.)
And now the New York Post also has a botched story.
This is what happened:
1) Officers of the First Marine Division are listening to their radios and overhear some 101st Airbone guys talking about finding some BM 21 rockets with some possible chemical weapon warheads. They weren't talking to the 101st guys directly, just listening in.
2) There's an NPR embed with the marines, so they tell the embed about it.
3) Embed then tells what he heard the Marine officer tell him what he overheard on the radio.
Nobody knows where these rockets are or anything more about them. They are NOT at the same location at the original Karbala find which does in fact appear now to be just pesticides (NBC and Reuters within the last 1-2 hours.) They ALSO are not the same location (apparently) as Najaf where there's the report of 101st Airborne with Mustard Gas blisters.
