L9 bar mine

Anti-tank blast mine

The L9 bar mine is a large rectangular British anti-tank landmine. The bar mine's principal advantage is its long length, and therefore its trigger length. A typical anti-tank landmine is circular, and a vehicle's wheels or tracks, which make up only a small proportion of its total width, must actually press on the mine to activate it. To increase the probability of a vehicle striking the mine, the mine's effective trigger width must be increased.
