RPG-40
The RPG-40 was an anti-tank hand grenade developed by the Soviet Union in 1940. Description
Upon contact,  of explosives contained within it were detonated and produced a blast effect. This enabled about  of armour to be penetrated and caused secondary damage, such as spalling, on contact with thicker armour. This made the grenade very effective against earlier German tanks, but ineffective against later models, such as the Panzer IV and the Panzer V, leading to the RPG-43 replacing it in 1943. Users
