It does work with a carbureted riding mower. Takes about an hour per
hole, though.

The 95% oxy 5% propane subterranian boom works a lot faster. I
don't know why the mix is so oxygen-rich, but that seems to be what
works in practice. Ignition is done with a robust and fairly powerful
spark, a piezo-popper apparently is not sufficient.

Cong tunnels were cleared with ethylene oxide/air explosions, it isn't
a new idea. Dispersed local overpressure pulse (as opposed to higher
but much more localized overpressure from HE) and flash heat are what
does the job.



The use of white phosphous was also used in the tunnels for denial.
The cystals would get a skin on them and stick to the walls of the
tunnel and when disturbed later...would flame back up.

Expect divots. You may also get the occasional ballistic rodent.

Wrong tunnels, Gunny.


Cong tunnels? Hardly. I dumped a bunch of Willy Pete into them on a
number of occasions. Usually in the form of grenades, but
occasionally by booby trapping an 81mm WP mortor round.
