I saw on British TV the other day that they are using trained cane rats
in Cambodia (?), who can smell the mines.

Funny that I knew you would respond that way. So, by your own
definition, I could easily say the same thing about you.

No. We should have bombed Hanoi early on, long before Nixon ever
entered into it. We were afraid of "escalation".

And what would that have gained you ?

Are you afraid of the principle of self-determination ?

GPR seems to work well for the US Army and Marines. They just
bought $338 million worth:

$300M = Over 17,000 Portable Mine-Detectors for US Troops

Posted 11-Aug-2006 09:52

In late December 2005, DID noted that the USA has spent $1 billion
on humanitarian land-mine removal over the last 10 years. A year
ago, on August 16, 2005, we noted a $38 million contract to CyTerra
for its AN/PSS-14 (formerly HSTAMIDS) Mine Detection Sets.

Someone must have liked them, because L-3 recently announced that
its March 2006 acquisition CyTerra has received a 10-year, $300
million contract for over 17,000 more sets as well as Sweep
Monitoring Systems for training, Training Target Sets, and worldwide
training and support. The value of the first order is approximately
$24 million. The US Army and Marines currently have about 2,000
delivered sets in their possession. See corporate release.

The AN/PSS-14 employs a state-of-the-art metal detector and ground
penetrating radar (GPR), coupled with an advanced microprocessor
array and software in order to achieve a high probability of
detection (in excess of 95%) for both large and small metallic and
even nonmetallic antitank and antipersonnel mines. They've even been
used to find underground pipes in civilian applications. It also
significantly reduces the number of false targets or alarms. The
apparatus weighs approximately eight pounds, uses standard batteries
and can be operated by a single Soldier. See this U.S. Army page re
all countermine equipment in current use:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The AN/PSS-14 Mine Detection Set (formerly known as HSTAMIDS) is a
vast improvement over today's metallic handheld mine detectors. It
employs a state-of-the-art metal detector and ground penetrating
radar (GPR), which are coupled with an advanced microprocessor array
and software to achieve a high probability of detection (in excess
of 95 percent) for both large and small metallic and nonmetallic
antitank and antipersonnel mines. It also significantly reduces the
number of false targets or alarms. If a mine is detected, audio cues
alert the operator. Built-in warning and test equipment also alerts
the operator of potential system malfunctions and assists
maintenance personnel in fault identification. The result is a
greatly improved system that protects the Soldier and enhances
his/her ability to detect landmines. The AN/PSS-14 weighs
approximately eight pounds, uses standard batteries and can be
operated by a single Soldier. The AN/PSS-14 is also being procured
by the U.S. Marine Corps as their Advance Mine Detector.
