I also googled... and came up with this. What can I say? I couldn't resist a challenge!
Journal of a Seasoned COBRA Veteran by Keith Pille Look under June 11, 1987.
In fact, I came across four separate web pages, but the text on all four appears to be the same. Now, whether Pille actually came up with the quote, himself, or whether this is someone else's quote, and he hasn't attributed it, I don't know. Certainly, the writing style of the quote you picked out seems slightly at odds with the rest of this journal entry. <Shrugs.>
Happy hunting!
