Yugoslavia. A plastic box mine that is usually coloured dark

Explosive charge: 200g TNT
Fuze, the fuze is a UPMAH-1 fitted with a detonator that lies
on its side within the explosive charge.
detonator makes it relatively easy (compared to the PMA-2 and
PMA-3) to detect with a metal-detector. The detonator is initiated
by a friction sensitive compound that can fail when wet. When
the compound dries out, the fuze may then function as designed.
version of the fuze with a plastic cased detonator is reported
to have been made. This would render the mine "metal-free",
so undetectable with a metal-detector.
