Russian soldier takes a break in Second Chechen War. Note modern rifle grenades on rifles in background.
With a tip of the boonie hat to John P, this comes from MicroBalrog: "The Mountain Echo – Small Arms in Mountainous Areas."
In Transdnistria and Karabakh, in 1992, a simple device was introduced that enabled using hand-grenades like Western rifle grenades. An F-1 grenade, fired from behind cover to a range of up to 80 meters, is far more effective than a VOG, which makes it extremely relevant in close-range combat.
The Russian F-1 hand grenade was first introduced in World War II and has been used in combat since all over the world. It is interesting that the Russians resorted to issuing adaptors of the US type (seen below) to project F-1s at greater distance.
