The original variant grenades entered service in Mar 1918, featuring cardboard bodies that were sometimes painted black. The MK. III A1 variant grenades had black-painted laminated paper bodies containing 7 ounces (about 0.20 kilograms) of flaked TNT explosives. The MK. III A2 variant grenades had waterproof asphalt-inpregnated fiberboard bodies, including the top and bottom sides (MK. III and MK. III A1 had metal tops and bottoms), containing 8 ounces (about 0.23 kilograms) of TNT. During the Pacific War, these grenades were often used to clear bunkers and other small structures.
