Bosnian Anti-Tank Mines

This is by no means a all-inclusive list of the mines used by the various factions during the civil war in Bosnia, however, these mines were known to be in service with the former Yugoslovian Army at the time the fighting began.  There were approximately 8 million mines still laid throughout Bosnia and the positions of only about 3 million of them are known, all in a country the size of the state of Tennessee.

TMA-1

Specifications

Type:  Anti-Tank, blast
Weight:  14.3 lbs
Diameter:  12.4 in
Height:  3.9 in
Main Charge:  11.9 lbs of TNT
Fuze:  UTMAH-1 chemical, pressure activated
Anti-Handling Fuze Wells: 1 on bottom center
Triggers:  Pressure
Triggering Action:  220 lb of pressure on the pressure plate
Construction:  Plastic

This AT mine is easily recognized because of it's distinctive corrugated top.  It is round in shape and is constructed of non-metallic materials.  The fuze is the standard chemical type with pressure on the mines top crushing a pressure sensitive chemical causing a spark that detonates the mine.  This mine is being replaced by more modern TMA type mines.


TMA-2

Specifications

Type:  Anti-Tank, blast
Weight:  16.5 lbs
Length:  10.25 in
Width:
  7.85 in
Height:  5.5 in
Main Charge:  14.3 lbs of TNT
Fuze:  2 x UTMAH-1 chemical, pressure activated
Anti-Handling Fuze Wells:  1 in the base
Triggers:  Pressure plate
Triggering Pressure:  265 to 705 lbs
Construction:  Plastic with some metal parts.

This rectangular non-metallic mine has 2 fuze wells on the upper surface.  When pressure is applied to the upper surface the flexible top of the mine moves downwards until the fuze well caps come in contact with one of the pressure fuzes which detonates the mine.  A hole is provided in the bottom to attach a anti-lift device and a folding carrying handle is attached to one side.


TMA-3

Specifications

Type:  Anti-Tank, blast
Weight:  14.6 lbs w/o fuzes
Diameter:  10.45 in
Height:  3.15 in
Main Charge:  14.3 lbs of TNT
Fuze:  3 x UTMAH-1 chemical, pressure activated
Anti-Handling Fuze Wells: 1 on bottom
Triggers:  Pressure
Triggering Pressure:  395 to 770 lbs
Construction:  Cast TNT with a fiberglass coating

This blast and waterproof mine is made of cast TNT with a fiberglass coating.  A canvas carrying handle is embedded in the side and there are 3 fuze wells on the top.  The fuzes are left exposed once installed and look like brown mushrooms.  There is a additional fuze well on the bottom for a anti-lifting device.


TMA-4

Specifications

Type:  Anti-Tank, blast
Weight:  13.9 lb w/ fuzes
Diameter:  11.2 in
Height:  2.4 in
Main Charge:  12.1 lb of TNT
Fuze:  3 x UTMAH-1 chemical, pressure activated
Anti-Handling Fuze Wells: 1 on bottom center
Triggers:  Pressure
Triggering Pressure:  441 lbs
Construction:  Cast TNT with a plastic coating

This mine is similar to the TMA-3 except that it has a smaller charge.  A rope handle protrudes through a hole in the body.


TMA-5

Specifications

Type:  Anti-Tank, blast
Weight:  14.5 lbs
Length:  12.3 in
Width:
  10.8 in
Height:  4.5 in
Main Charge: 12.1 lbs of TNT 
Fuze:  UANU-1 chemical, pressure activated
Anti-Handling Fuze Wells:  4 in the base
Triggers:  Pressure plate
Triggering Pressure:  220 to 660 lbs
Construction:  Plastic

This is a square, plastic bodied mine with a single fuze well in the center.  The mine has 4 holes in the base of the mine for attaching anti-lifting devices and a small rope carrying handle attached to one side.  The UANU-2 chemical action fuze is stored in a shipping well along one edge of the mine.  The each corner has a plastic leg sticking upwards to aid in stacking the mines.  These mines have been found stacked up to 6 deep in order to enhance it's effect


TMM-1

Specifications

Type:  Anti-Tank, blast
Weight:  18.9 lbs
Diameter:  12.2 in
Height:  3.5 in
Main Charge:  12.3 lbs of Trotyl
Fuze:  UTMM-1 Pressure
Anti-Handling Fuze Wells: 2 on bottom
Triggers:  Pressure
Triggering Pressure:  287 lbs, 154 lbs w/o pressure plate
Construction:  Sheet metal

The TMM-1 is a copy of the WWII German Tellermine 43 (also called the mushroom mine).  This mine is constructed of sheet metal and is comes in two parts, the mine body and a screw on pressure plate.  It is fuzed by a mechanical fuze designated the UTMM-1.  Pressure on the pressure plate forces the firing pin down until a shear pin breaks allowing the firing pin to contact the primer which in turn detonates the mine.  This mine has been found with the pressure plate removed, this cuts the pressure required to set off the mine in half.  There are 2 anti-handling fuze wells on the bottom of the mine.  The standard anti-handling device is a pull switch with a 4 in. wire attached to a stake driven into the ground under the mine.  This mine is extensively used on roadblocks where it is surface laid.


TMRP-6

Specifications

Type:  Anti-Tank, blast and jet
Weight:  15.9 lbs
Diameter:  11.4 in
Height:  5.2 in w/o tilt rod
Main Charge:  11.25 lbs of cast TNT
Fuze:  UTMRP-6
Anti-Handling Fuze Wells: 1 on bottom
Triggers:  Pressure and tilt rod
Triggering Pressure:  330 lbs on pressure plate or 2.9 lbs laterally on tilt rod
Danger Area:  Lethal-25 m, danger to vehicles to 45 m when laid on its side, Casualty-100m
Construction:  Plastic body with metal parts

This is a very dangerous mine because it uses the twin explosion principal and a shaped charge to do a extensive amount of damage to it's target.  The mine is armed using a special key to align the initiation train, then the tilt rod is inserted.  A internal clockwork mechanism arms the mine 1 to 4 minutes later.  Once armed, pressure on the pressure plate or laterally on the tilt rod detonates a small charge of black powder which blows off the top of the mine and the above soil, exposing the main charge and the convex steel plate.  The shaped charge then fires blasting the plate through the targets armor.  The anti-handling fuze well on the bottom can be fitted with a electrical detonator for command detonation.  This mine has been found laid horizontally in embankments along roads and also with tripwires attached to the tilt rod allowing it to function in a APERS role.
