Use:
The ground burst antitank mine M75 can be emplaced only by the ground vehicle mine dispenser M128. The mine may be used in mixed minefields or by itself against heavy tanks and other types of heavy tracked and wheeled vehicles.



Description:
The mine is green, cylindrical in shape, and fabricated of thick-wall steel tubing. It has an internal safing and arming device, an electronic assembly, and a power supply. Some of the M75 mines have an antidisturbance switch within the mine, as indicated by the last digit in the lot number. A lot number ending with a "-2" indicates that the mine has an antidisturbance switch; a lot number ending with a "-1" indicates no switch. The mine is set for a specific (normal) selfdestruct time by the manufacturer; however, during operations it can be set for a long self-destruct time, depending on the mission requirement. The mines are shipped and stored in a sealed, desiccated container.
The container holds eight sleeves, each containing five mines (one mine with an antidisturbance switch and four mines with no antidisturbance switch), for a total of 40 mines per container. The containers are palletized, with six containers per pallet.

Functioning:
Partial arming results from the angular velocity obtained as the mine travels through the launcher of the dispenser. A magnetic impulse provided by two transmitter coils located in the launcher muzzle initiates a low-order detonating primer, which activates two reserve batteries. The batteries provide the electrical power to complete the arming cycle after the mine comes to rest on the ground. The mine is completely armed in 40 to 60 seconds after launch and is then ready to detect a target. The mine will function in response to any of the
following conditions: (1) vehicle passing over the mine, (2) physical disturbance of the mine, (3) expiration of self-destruct time, or (4) power rundown.
