Mined area Indicators – OZM scene

 

 

Sheet 45     OZM scene
(Page 1)

The picture shows an area of woodland outside a small town. The area was mined with OZM-4 bounding fragmentation mines and MAI-75 blast mines to prevent attackers using the trees as cover.

If you look closely at the picture you may see some indications of the area being mined.

Suggested message(s):

  • The more you know about an area, the easier it is to judge whether or not it is dangerous.
  • Always try to keep to paths when in unknown areas.

 


Sheet 46     OZM scene
(Page 2)

The red arrows on the picture show the indicators that you may have noticed.

The detailed pictures show:

A – Metal tripwire stakes. One has rusted badly, the other is new.

B – Wooden tripwire stakes. One has begun to rot, the other is new.

C – AN OZM-4 bounding fragmentation mine with an MUV-2 fuze. This mine has a cast-iron body 91mm in diameter (just over 3½”). It contains 170g TNT. When initiated, the mine body is thrown into the air until it pulls a wire attached to its baseplate tight. The main charge then explodes, scattering the area with cast-iron fragments.

D – A wooden tripwire spool and wire, dropped or cast aside when the mines were being laid.

E – Caps from the OZM-4. The fuze-well caps on the left may be discarded when the mines are laid. The winged cap on the right is replaced in the mine after the main charge detonator has been fitted.

F – The base of an OZM-4 mine that is left in the ground when it explodes. The wire tether may be left exposed after the mine has detonated.

Suggested message(s):

  • If you look carefully, it may be possible to see something that is a warning of danger.
  • Where tripwire mines are laid, some indicators are above the ground.
  • Although no blast mines can be seen, it is very likely that pressure initiated blast mines will be close by.
