The DOD also funds development of guided, chemical, biological and nuclear weapons, and just about every other way to kill a man you can think off.
"Agent Orange" was pretty much militarized by the University of Hawaii under a DOD grant during the late 60's, and they've coordinated with the USAF and the CIA and provided research and analysis to optimize the dispersal methods and study it's effects during it's combat use over Vietnam.
I'm not actually sure this isn't sarcasm.
