Hawkins Grenade

The Grenade, Hand, Anti-tank, No. 75, also known as the Hawkins grenade was a British anti-tank hand grenade used during World War II. It was one of a number of grenades developed for use by the British Army and Home Guard in the aftermath of the Dunkirk evacuation. The grenade first appeared in 1942, and was designed to be more versatile than previous grenades, such as the Grenade, Hand, Anti-tank No. 73 and the Grenade, Hand, Anti-Tank, No. 74.

It was rectangular in shape, about 150 millimetres (5.9 in) in length and 75 millimetres (3.0 in) in width, and contained approximately 0.45 kilograms (0.99 lb) of explosive. When a vehicle drove over the grenade, it cracked a chemical igniter and leaked acid onto a sensitive chemical, which detonated the explosive. Multiple grenades were often used to destroy tanks or disable their tracks, and the grenade could also be used as a demolition charge. It was used by the British Army and the United States Army, with the former using it until 1955 and the latter also creating their own variant, the M7 anti-tank mine.
