True story.. we had a Commando Vault in our area. C-130 dropping a 10,000lb bomb out the back and it was a dud. What to do? One FAC had some -100s in the area and asked them to come over and strafe an area. Lead asked what the target was. The FAC told him he just needed to cook some stuff off. Lead persisted. Finally the FAC told him he wanted the guy to walk some 20mm through an area with the big bomb.
Lead said, "....**ck you. Two, let's go button four and RTB."
