Which naturally reminds me of a story.
Back in my days with the Chemical Biological Incident Response Force (CBIRF), we used to host vendors who would come display their gadgetry. Presumably, these were designed to deter, detect, or defend against the unsavory chem/bio/radiological hazards. My favorite vendor was the guy who brought a lovely assistant with him and encouraged her to verbally engage the Marines. I guess he hoped a bunch of LCpls would somehow convince the command: “Buy whatever the hot chick is selling!”
At one of these vendor days a Marine Chief Warrant Officer was inspecting some type of detection device. Being a chem/bio/radiological/nuclear (CBRN) defense specialist and in charge of detection and reconnaissance platoon he had some professional interest.
The vendor went on and on boasting on the virtues and performance of his device. Then he made a mistake. He claimed the device was indestructible.
“Really?” the CWO replied to this new claim.
“Absolutely,” The vendor went on. “You can do whatever you want to that thing. You can’t break it.”
The CWO was dubious. “I don’t know about that.”
“No really,” the vendor assured him. “You won’t be able to break it. Go on, try it.”
“Are you sure?”
“Go for it.”
The CWO took the device and promptly dropped it into a bucket of water. It failed to function after that.
Once again, Marine ingenuity overcomes modern science.
