Can you be an idiot and fly a fighter jet or helicopter? Can you be an idiot and run a tank? Can you be an idiot and figure out exactly where you need to place the crosshairs to take out the enemy from 800 yards away?
Well, let's see. These days fighter jets, helicopters, and tanks all have multiple onboard computers. Some run the engines. Some help pilot the machine (some even pilot entirely under certain conditions). Some aircraft can't be flown without them (stealth wings aren't all that aerodynamic), except perhaps into terrain. Some assist or accomplish fire control, including making air resistance and wind corrections for where to place those crosshairs. Some link various vehicles (AWACS, tanks, launcher sites, etc.) so that they become fighting systems.
Yeah, you can be much more of an idiot than meets the eye and still run the equipment. When a pilot or gunner delivers a "smart bomb" down the smokestack of a specific building, who really accomplished that incredible feat? The pilot or gunner had to be there, sure. But that smart bomb hit its target courtesy of Bendix, Raytheon, Texas Instruments, Motorola, Hughes, EG&G, and many other organizations whose efforts are purchased by the military.
I know this because I have worked for a couple of these companies. I turned down a civilian Navy position at the David Taylor Naval Ship R&D Center in Carderock, MD, because they couldn't touch what I was earning doing the same work for a contractor. I have a college buddy who works for Lockheed and has worked for Inmarsat who "can't really say what he does".
What do you think he means by that?
Study hard, get good grades, take an interest in something other than beer, and you might become more valuable in the defense of your country by sitting your ass in a laboratory than by hanging it out there to be shot at.
That is what Kerry was saying, and that's the way it is. It was an admonishment aimed at students. If enlisted men want to infer insult, let them.
