The RGO hand grenade (Ruchnaya Granata Oboronitel'naya) is a defensive Russian fragmentation hand grenade. It consists of a double layered aluminium pre-fragmented body. It is very similar to the offensive RGN hand grenade. It uses the UDZS dual action fuze, which has both impact and time delay functions. The impact fuze activates after a pyrotechnic delay of 1 to 1.8 seconds. If the impact fuze has not triggered the grenade after 3.2 to 4.2 seconds a second pyrotechnic delay triggers the grenade. The fragments produced by the grenade generate a lethal radius of between 6 and 20 meters, with the safety radius being 100 meters. the grenade is still in production in Russia and Ukraine and is in service with a number of countries.
