The No.68 anti-tank grenade is one of the first cumulative anti-tank grenades to be introduced into the arsenal of troops. It was characterized by its simple construction and, at the time of its introduction into service, sufficient penetration against enemy armoured vehicles when used properly.
The grenade was designed to be fired from infantry rifles (e.g. Lee-Enfield) using the No. 1/ No.2 Discharger attachment (grenade launcher). When impacting the technique at a 90° angle, the cumulative warhead provided armour penetration up to 52 mm (2 in) thick. The grenade was stabilized in flight by a simple rib stabilizer. The grenade was inducted into service in 1940, being withdrawn from the first-strength units in 1942, and lasted in Home Guard units until 1945. A total of 6 sub-variants were produced, designated Mk.I - Mk.VI.
The total weight of the grenade was 0.894 kg, of which 0.156 kg was the explosive charge (picric acid (TNP or lyddite), Pentolite, or a combination of RDX and beeswax).
