A Sticky or Sock Bomb is an anti-tank weapon available exclusively to Paratroopers. The trooper must be close to the target in order to lay the timed charge, and must retreat quickly to escape the explosion, which is capable of destroying just about any vehicle.
When the sock bomb is on a tank and the tank is destroyed before the bomb blows up, the sock bomb will lie on the ground and explode. They can also destroy rocks.
The Sock bomb is composed of a sock, a covering of grease to make the bomb stick, and a stuffing of explosives. When applied to the side of a vehicle, the fuse is lit and the explosion will happen in about 6 seconds. It has a large gib radius, about the size of TNT explosions. Be careful.
The sticky bomb is also probably a reference to Saving Private Ryan, just like in the description of the Flak 38.
The Sticky Bomb, also known as S.T. Grenade, was British engineered anti-tank weapon designed to be used by infantry. The grenade consisted of nitroglycerin inside a glass sphere, surrounded by strong adhesive. The layer was covered by sheet-metal cover which was designed to fall away when a pin was pulled by the soldier using it. The grenade would be then slammed (either thrown or by hand) to the side of a tank or other vehicle. 2nd pin was then pulled to activate the firing mechanism which detonated the nitroglycerin. The design proved to have faults; the adhesive possessed a danger of getting stuck to the uniform of the user, especially when the weapon was thrown, and the handle of the grenade could harm the user they were in line with it when the grenade detonated. The grenade was estimated to be able to penetrate 25mm of armor, making it largely ineffective against most tanks. 2 500 000 were produced during the war and were issued to British Home Guard units, Australian Army units, Allied troops at Anzio Beachhead, French Resistance and Allied troops at North Africa. Six German tanks were destroyed at the North Africa front by these weapons.
