Good Stuff Cyclic.
I'm now going to get on the phone to "Covey Rider" and see if he hasn't guilded the lilly a bit.
My own research showed the first BLU-82 being used in Laos in Oct 70.
I don't think any BLU-82's where used in Cambodia. The Camboadia operations in April 70, fell under the PATIO programme, and I see no record of any BLU-82's on PATIO.
