yield=The Type 99 (Hako-Baku-Rai) mine was a Japanese anti-tank weapon used during the Second World War. It entered service in 1939. Four magnets were attached to the casing, along with an external fuze. The fuze had a time delay, which enabled it to be used as an anti-tank hand grenade, or a demolition charge. Once the safety pin was removed, it was armed, striking the fuze ignited a powder delay train. The mine detonated after a five to ten seconds delay, giving enough time for it to be thrown.

The mines could be stacked, held together by the magnets for greater effect. When used individually the mine could penetrate approximately 0.75 inches (19 mm) of steel, with two mines stacked it can penetrate 1.25 inches (32 mm) of steel. US Army Field Manual FM 5-31]
