An impact grenade is a hand grenade designed to detonate upon striking a surface, rather than using a time-delay fuze. The design prevents its target from taking cover or throwing the device back at its user.
Types of impact grenade
The Discushandgranate (Discus hand grenade) was a German impact grenade designed during World War I. Inside the grenade, four striker pins were held safe by a pen. When thrown like a discus, the pins would release the pen due to centrifugal force, arming the device. On impact, the striker pins would return, setting off the grenade.
The RGO (Ruchnaya Granata Oboronitel'naya) hand 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.

Upon spawn the player gets only 1 RGO. The name "Impact" grenade is a bit misleading, as the grenade actually detonates almost a second after impacting a solid surface. Should the grenade somehow fail to reach ground, or land without a hard enough impact, a secondary timed fuze activates later. Up to 80 damage can be dealt to the opponent.
Compared to the M67 and V40, the RGO outperforms them in close quarters due to its impact fuse and does more direct damage than the V40. However, the V40 has a superior range compared to the RGO and M67, and the M67 does the most damage out of all three of the fragmentation grenades. The RGO and M67 also take a very considerable time to resupply due to their damage, taking 25 seconds to resupply from an Ammunition Box, while the V40 only needs 13 seconds to resupply.
After Battlefield 4's Fall 2014 patch, players can now carry only 1 RGO Impact (or 2 with GRENADES specialization), previously players could carry 2 by default. The RGO's inner blast radius was slightly decreased as well, to 1 meter from 1.65, and its resupply time was lengthened considerably to 25 seconds from its original 7 seconds. These changes were made to discourage grenade spamming, and make grenades more of a tactical tool in combat.
— In-game description
The Impact Grenade in Battlefield 1 uses the German Discushandgranate as its model. In the "Battlefield 1 E3 Teaser Trailer", an icon for the discus grenade is briefly visible while demonstrating the Anti-Tank Grenade. It is available to all regular infantry kits once purchased.
It functions similarly to the RGO, detonating a split-second after striking a surface.
