Ya gotta wonder who tried this the first time. "No, Sarge... Really... ".
But it's just intuitively a great idea. Genius.
It's almost too cool to be true, though. How many spaces are really rigged with trip wires over there? Is it a common technique of the bad guys?
When clearing buildings in a hostile area? Yep.
We have used it for about 10 years. We would clear "Impossible City" at Ft Ord, and EVERYONE had at least 2 cans of silly string.
The stuff really works, and the bad guys ARE wiring things everywhere.
