dcdryer -- Yes, the 9th PSYOPS BN is involved in tactical dissemination of POTF product, not psychic assassination attempts. But that doesn't make the sign any less amusing in this context.

Parenthetically, my wife remembers the military purchasing a large number of goats during the 1980s, when the "psychic SOF" stuff was going on. These requests weren't unusual -- the Army trains field medics in some cases by injuring sedated caprines and having the trainees stabilize them -- except that the military was specifically requesting "fainting goats," a breed that has a muscle chloride channel mutation that disrupts chloride conductance in the muscles. When the goats are startled, they suffer a kind of acute mytonia and fall over: although they're awake and unharmed, they appear to be "fainting."

This is entirely speculative on my part, but it seems possible if not probable that the "psychic warrior" crew used fainting goats as their test subjects. Unfortunately, since the goats do tend to fall over at even minor disturbances (and do so in flocks), they wouldn't really be suitable for heart-stopping psychic assassination training. You really can make them fall over just by looking at 'em funny.

And if you're doubting that the military can spend large (if relatively insignificant) sums on totally bizarre dead-ends, I recommend Sharon Weinberger's "Imaginary Weapons," a brilliant look at the pseudo-scientific underworld of DARPA development.
