Make war not...hey, does anyone else feel like microwave popcorn?

Apparently, the U.S. Army's "pain ray" is being recalled from Afghanistan without ever being used in action. Feelings about an invisible microwave beam weapon aside (yeah, I admit, it seems kinda cool), does anyone else see the irony of the test group in this video being military personnel playing "non-violent" protesters in favor of world peace while hurling rocks and other debris? Apparently the anti-Gandhi wasn't available.
