Teller mine

With explosives sealed inside a sheet metal casing and fitted with a pressure-actuated fuze, Teller mines had a built-in carrying handle on the side.

Containing little more than 5.5 kilograms of TNT and a fuze activation pressure of approximately 200 lb (91 kg), the Teller mine was capable of blasting the tracks off any World War II-era tank or destroying a lightly armored vehicle.

Thereafter, any attempt to disarm the mine by unscrewing the pressure plate (or screw cap) to remove the fuze will automatically release the spring-loaded firing pin inside it, triggering detonation.

Since it is impossible to determine which fuze type has been installed, no pressure plate or screw cap can ever be safely removed from a Teller mine.

[2] To hinder demining, all Teller mines featured two additional fuze wells (located on the side and underneath) to enable anti-handling devices to be attached, typically some form of pull-fuze.
