God gun
n.— «Soldiers fire blanks, of course. Team members wear harnesses with sensors that register when they’ve been hit, a sort of heavy-duty version of laser tag. When an explosive device goes off, an impartial observer with a “God gun” eyeballs the radius of the explosion and zaps those impacted.» —“Dead-On Competition” BusinessWeek Aug. 21, 2006.
