Was "Jitterbugging" a term used for collapsing tunnels with a tank, circa Vietnam?

Factual Questions
1

I need some help with a military slang/terminology question…I seem to recall hearing or reading, ages back, that the term “Jitterbugging” was used by US forces in Vietnam for a method of collapsing tunnels using a tank—by parking on top of the underground tunnels, and rotating the vehicle in place on it’s treads, or putting it in “neutral” and gunning the engine…something like that. The vibration and weight doing the work.

However, double-checking this online to be sure, aside from an unrelated Vietnam-era tactic, the only references I can find are one of my own SDMB posts, and two or three conspiracy nutjob pages going on about Waco. And while military conspiracy loonies are entertaining, they’re hardly a good source for historical accuracy.

I’m pretty much willing to write the memory up as an old brain fart on my part, but I’m curious to find out if there was any germ of fact behind it to begin with (I dunno, maybe it was from a bad movie, or the tankers actually called it the “Watusi” or something). Can anyone help?

I think if your tunnel were collapsing around your ears, you would be scrambling around like a jitterbug trying to get out.

In all seriousness, if you go to youtube and watch some jitterbug dancing, it features a lot of twirling and foot stamping. Sorta like the tanks were doing.

Here’s some info on jitterbugging, but it doesn’t seem to indicate what you describe.

I was born in 1967 so I’m obviously not old enough to have heard it first hand. I used to be a tanker and I have never heard the term. The link above shows that it meant something else. I can say that as described the technique (whatever it may have been called) seems very very stupid. If successful you are now in a hole that you might not be able to get out of. And the only time you should neutral steer is on a concrete pad unless its an emergency. On uneven terrain it’s a sure way to throw a track.
