How many people can one grenade kill?

The lethality of a grenade depends on various factors such as its type, size, explosive power, and the environment in which it detonates. In a confined space, a hand grenade can potentially kill or injure multiple individuals within a radius of about 15-30 feet. However, in an open area, the effective range of a grenade is typically around 5-10 meters, with the potential to cause casualties to anyone within that radius. It is important to note that the actual number of people killed by a single grenade can vary significantly based on these factors.
