The Type 99 mine (Hako-Baku-Rai) was a Japanese anti-tank weapon used during the Second World War wich also know as the Turtle Mine. It entered service in 1939. Four magnets were attached to the casing made of hemp cloth, along with an external fuze. The fuze had a time delay, which enabled it to be used as an anti-tank hand grenade (not ingame), 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 (ingame 5sec), 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. In FHSW is the possibility to use single mines but also in two packs or four packs. A kit have 4 mines. When you use the 4 pack, you will use all your mines together. When you use one mine and you doesn't resupply your mines, you can only use your single mines or the double pack.
