Just a quick footnote to what Furb noted, that is
it takes more than one mine to make an effective
mine field. Of course if all you want to do is take
out the first or second guy in a column as they
come down a trail, that's one thing, but to make
the whole team stop, or back up you'll need at
least a dozen mines laid out in a pattern not only
on the trail but on both sides as well.
BTW, the mine shown in those earlier video clips
looks almost identical to a patented design which
was marketed some years ago by a Canadian firm.
I should know, becuse I used to sell them on my
old website. They are very simple to make and
very effective, especailly if you use the three
outlet spray nozzle. Only real drawback and this
applies to all such mines, is they lack any noise
when they're detonated.
Here's a link ot a clip which shows a paint
claymore mine which not only paints you, it'll
also scare the heck out of you. Only trouble
is the makers restrict sales to DOD end users
