The RGO Impact Grenade is a Russian fragmentation device that features an impact-sensitive fuse as its primary detonator. This is in contrast with time-delay fuses such as that seen on the American M67, and similar to devices like the common 40mm grenade. A secondary time-delay fuse ensures the grenade explodes about four seconds after it is armed. It is otherwise similar in construction to a typical hand grenade.
The grenade was seen as an option in alpha gameplay at Gamescom 2013, and mentioned in commentary with DICE Creative Director Lars Gustavsson, though it has not been seen used in battle or on the killfeed.
The RGO Impact grenade is introduced in Battlefield 4 as one of many options for the player's kit.
