The following is not my work. I copied it from another forum in case it's of interest.
"I happened across this military document (originally produced in the 1970s) on how to apply forest fires as a military weapon.

It was given DARPA authority in 1983 and produced to be distributed by authorised US Government Agencies and their contractors and goes into great detail of these strategies over some 170+ pages."
Excellent find! Will be sharing
