R2M2 was manufactured in South Africa and has been used in large
numbers throughout Southern Africa, especially Zimbabwe, Mozambique,
Zambia, Angola, and Namibia. It is a pressure operated minimum-metal mine. See the R2M1/2 Factsheet for more detail.
Colour: various shades of green and beige (fading to white if
exposed for long periods)
Main charge: 58g RDX/Wax
booster charge screws into the base of the mine. The cap of
the booster may be extended into a plastic spike as shown above.
This was intended to prevent mine movement after placement.
the metal content seems relatively large, it has proven particularly
difficult to detect with a metal-detector. The picture below
shows the metal content, comprising three ball bearings, a coil-spring,
a pin and an aluminium-alloy cased detonator.
plastic parts of the mine become brittle with prolonged exposure
to UV. When the plastic cracks the mechanism holding the spring
can be released. This is probably the cause of the spontaneous
detonations have been recorded.
