Strvm 6

Stridsvagnsmina 6 [Antitankmine 6] is intended to be used against AFV.
The mine is designed to kill, rather than disable, armored vehicles.
It is a magnetic mine, detonated by the passing of a metal mass of at
least 750 kg. As a magnetic mine, it may (50% chance) be detonated by
the passing of a mine detector over it, or even the probing of a knife
blade or similar-sized metal mass (10%) in direct contact. The casing
is non-metallic, and the mine is two levels harder to detect by a mine
detector. This mine is unaffected by overpressure, or countermeasures
such as mine rollers, plows, and flails. It can also distinguish between
a genuine vehicle and a magnetic signature duplicator. Disarming this 
mine is an Impossible: Combat Engineer task unless the proper key is
employed (common in engineer demolitions  chests of the countries using
the mine). This mine is used by Sweden, Germany, Netherlands, and Canada.
