The shell of the No 69 grenade is composed of hard plastic Bakelite, exploding on impact it shattered without producing fragments like a metal bodied grenade. To use the No 69 bomb the screw-off cap was removed, and the grenade was then thrown, a linen tape with a curved lead weight on the end automatically unwrapped in flight, freeing a ball-bearing inside the fuse which armed the all-ways fuse in flight and the grenade exploded on impact.

Grenade, Hand, Anti-tank, No. 75, MK.1. more commonly known as the Hawkins grenade. On the top of the grenade is a plate, under which the user would insert a chemical igniter, when a vehicle drove over the grenade, its weight crushed the plate, which in turn cracked the igniter; this then leaked acid onto a chemical which detonated the charge. The grenade was designed so that it could either be thrown at a vehicle like an ordinary anti-tank grenade, or used as an anti-tank mine. It was also fitted with areas where blasting caps or cordex could be placed, so that it could be used as a demolition charge. The grenade saw service with the British Army until 1955. The United States Army also used the grenade, as well as developing their own variant known as the M7 light anti-tank mine.When used in an anti-tank role, a number of the grenades could be strung together in a daisy chain and then placed across a road to damage armoured vehicles. When grenades were grouped together, they were capable of disabling a medium tank. The Hawkins was also used in other roles, such as breaching walls and destroying sections of railway track.
